Oracle SQL Tutorial 26 - UTF-8 and UTF-16
 
05:46
UTF-8 and UTF-16 are different encodings for the Unicode character set. Let's discuss UTF-8 first. UTF-8 is what is known as a variable-length character set. This means that the amount of storage a character takes up depends on what character it is. For example, if we store the character A, it will only take up one byte. In fact, ASCII is a subset of UTF-8. That means UTF-8 encoding can work with ASCII data. If you are new to computer storage, a byte is a very small amount of information. The smallest thing a computer can store is a bit. 1 or 0. On or off. There are 8 bits in a byte, 1024 bytes in a kilobyte, 1024 kilobytes in a megabyte, 1024 megabytes in a gigabyte, and 1024 gigabytes in a terabyte, and 1024 terabytes in a petabyte. Considering it is completely possible for a database to be multiple petabytes, you can understand that a byte is very small. If you store a non-English character, the size of UTF-8 will increase to 2, 3, or 4 bytes. If you think back to when we used the VARCHAR data type, we passed in 50 CHAR. The reason we throw in that CHAR is that the default for Oracle is 50 characters. Now you can understand why adding the CHAR might be important. If a character can take up multiple bytes, you cannot guarantee 50 characters. Now, on to UTF-16. UTF-16 is also a variable length encoding, but it differs in that It is either 2 or 4 bytes. That means to store an A, it now takes two bytes rather than one. Even though a byte is so small, when you are storing billions of characters, an unnecessary byte really adds up to a lot of wasted storage. We can only represent so many characters with 2 bytes. When we run out of options, we move to four bytes to allow for other characters. Which do we use? It often depends on what platform you are on and also what languages you are working with. For example, if you are working with Asian language, UTF-16 stores each character in 2 bytes while UTF-8 stores each character in 3 bytes. So you could save space by using UTF-16. Additionally, UTF-16 works better when you are writing code in Java or something from Microsoft .NET because UTF-16, or a subset of it called UCS-2, is widely adopted. Other than that, UTF-8 will be the one you want. Now that we have built a pretty good foundation of character sets, we can now continue our discussion of data types. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Oracle SQL Tutorial 28 - CHAR Part 2
 
03:33
Now this video is a continuation of the last video. I decided to break the video up into sections so they didn't cover so much information and drag on for 10 minutes. This video we are going to talk about the length of CHAR. Now it is important to remember that CHAR is a fixed-length data type. This means that every row's value for this column is going to have the same length. The length is given to the database by specifying the length in parenthesis, such as CHAR(10). If you give a value shorter than that, it will be padded with spaces. What range is allowed though? The lowest is actually one. The highest is 2000. Now, remember that Oracle allows either the specification of CHAR or BYTE. The limit of 2000 is actually 2000 bytes. What happens if you put 2000 CHAR? Well, Oracle actually lets you do that. What is the problem with this though? The problem is that not all characters are 1 byte. This means that our 2000 CHAR is inaccurate. This will only work with 1 byte characters. This might not seem like a big problem, but it can lead to runtime errors in code that uses our database. A runtime error is when our code runs and in certain circumstances we get an error and others we do not. If we allow a user to insert up to 2000 characters, but they decide to use multibyte characters such as Chinese, we will get an error. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Support me! http://www.patreon.com/calebcurry Subscribe to my newsletter: http://bit.ly/JoinCCNewsletter Donate!: http://bit.ly/DonateCTVM2. ~~~~~~~~~~~~~~~Additional Links~~~~~~~~~~~~~~~ More content: http://CalebCurry.com Facebook: http://www.facebook.com/CalebTheVideoMaker Google+: https://plus.google.com/+CalebTheVideoMaker2 Twitter: http://twitter.com/calebCurry Amazing Web Hosting - http://bit.ly/ccbluehost (The best web hosting for a cheap price!)

Unicode
 
44:40
Unicode is a computing industry standard for the consistent encoding, representation and handling of text expressed in most of the world's writing systems. Developed in conjunction with the Universal Character Set standard and published in book form as The Unicode Standard, the latest version of Unicode contains a repertoire of more than 110,000 characters covering 100 scripts and various symbols. The standard consists of a set of code charts for visual reference, an encoding method and set of standard character encodings, a set of reference data computer files, and a number of related items, such as character properties, rules for normalization, decomposition, collation, rendering, and bidirectional display order (for the correct display of text containing both right-to-left scripts, such as Arabic and Hebrew, and left-to-right scripts). As of June 2014, the most recent version is Unicode 7.0. The standard is maintained by the Unicode Consortium. Unicode's success at unifying character sets has led to its widespread and predominant use in the internationalization and localization of computer software. The standard has been implemented in many recent technologies, including modern operating systems, XML, the Java programming language, and the Microsoft .NET Framework.

CppCon 2018: Bob Steagall “Fast Conversion From UTF-8 with C++, DFAs, and SSE Intrinsics”
 
01:09:40
http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2018 — UTF-8 is taking on an increasingly important role in text processing. Many applications require the conversion of UTF-8 to UTF-16 or UTF-32, but typical conversion algorithms are sub-optimal. This talk will describe a fast, correct, DFA-based approach to UTF-8 conversion that requires only three simple lookup tables and a small amount of straightforward C++ code. We'll begin with a quick review UTF-8 and its relation to UTF-16 and UTF-32, as well as the concept of code units and code points. Next, we'll look at the layout of bits within a UTF-8 byte sequence, and from that, show a simple algorithm for converting from UTF-8 to UTF-32. Along the way will be a definition of overlong and invalid byte sequences. Following that will be a discussion of how to construct a DFA to perform the same operations as the simple algorithm. We'll then look at code for the DFA traversal underlying the basic conversion algorithm, and how to gain an additional performance boost by using SSE intrinsics. Finally, we'll compare the performance of this approach to several commonly-available implementations on Windows and Linux, and show how it's possible to do significantly faster conversions. — Bob Steagall, KEWB Computing CppCon Poster Chair I've been working in C++ since discovering the second edition of The C++ Programming Language in a college bookstore in 1992.

Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

The encoding is defined by the Unicode standard, and was originally designed by Ken Thompson and Rob Pike. The name is derived from Unicode (or Universal Coded Character Set) Transformation Format – 8-bit.It was designed for backward compatibility with ASCII. Code points with lower numerical values, which tend to occur more frequently, are encoded using fewer bytes. The first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single octet with the same binary value as ASCII, so that valid ASCII text is valid UTF-8-encoded Unicode as well. Since ASCII bytes do not occur when encoding non-ASCII code points into UTF-8, UTF-8 is safe to use within most programming and document languages that interpret certain ASCII characters in a special way, such as "/" in filenames, "\" in escape sequences, and "%" in printf. UTF-8 is the "mandatory" Unicode character encoding for the World Wide Web; has been the dominant encoding (of any kind) since 2009, and as of October 2018 accounts for 92.6% of all web pages (some of which are simply ASCII, as it's a subset of UTF-8) and 95.1% of the top 1,000 highest ranked web pages. The next-most popular multi-byte encodings, Shift JIS and GB 2312, have 0.4% and 0.4% respectively. The Internet Mail Consortium (IMC) recommended that all e-mail programs be able to display and create mail using UTF-8, and the W3C recommends UTF-8 as the default encoding in XML and HTML.

UTF-EBCDIC | Wikipedia audio article

It is meant to be EBCDIC-friendly, so that legacy EBCDIC applications on mainframes may process the characters without much difficulty. Its advantages for existing EBCDIC-based systems are similar to UTF-8's advantages for existing ASCII-based systems. Details on UTF-EBCDIC are defined in Unicode Technical Report #16. To produce the UTF-EBCDIC encoded version of a series of Unicode code points, an encoding based on UTF-8 (known in the specification as UTF-8-Mod) is applied first (creating what the specification calls an I8 sequence). The main difference between this encoding and UTF-8 is that it allows Unicode code points U+0080 through U+009F (the C1 control codes) to be represented as a single byte and therefore later mapped to corresponding EBCDIC control codes. In order to achieve this, UTF-8-Mod uses 101XXXXX instead of 10XXXXXX as the format for trailing bytes in a multi-byte sequence. As this can only hold 5 bits rather than 6, the UTF-8-Mod encoding of codepoints above U+009F is generally larger than the UTF-8 encoding. The UTF-8-Mod transformation leaves the data in an ASCII-based format (for example, U+0041 "A" is still encoded as 01000001), so each byte is fed through a reversible (one-to-one) lookup table to produce the final UTF-EBCDIC encoding. For example, 01000001 in this table maps to 11000001; thus the UTF-EBCDIC encoding of U+0041 (Unicode's "A") is 0xC1 (EBCDIC's "A"). This encoding form is rarely used, even on the EBCDIC-based mainframes for which it was designed. IBM EBCDIC-based mainframe operating systems, such as z/OS, usually use UTF-16 for complete Unicode support. For example, DB2 UDB, COBOL, PL/I, Java and the IBM XML toolkit support UTF-16 on IBM mainframes.
