Subject: A few good articles on Unicode
Reply to author | Forward | Print | Individual message | Show original | Report this message | Find messages by this author

To add a little fuel to the discussion (and to help dispel some rumors,
myths, and legends about Unicode) I present you with Tim Bray's 4-part
trilogy of articles on Unicode, why it's important, and why you should use
it. The first article provides a nice overview, even mentioning some of the
political and technical difficulties of CJK languages and Unicode (as well
as the previously-mentioned gaiji). The second article discusses character
strings in general. The third, perhaps most relevant to the Ruby Unicode
discussion is an exploration of characters versus bytes, and how the various
encodings work. The fourth article discusses Java's use of UTF-16
internally, and why that may be a good or bad thing.

At any rate, they're entertaining to read and cleared up a number of my own
questions about Unicode. Perhaps they will help the rest of us in the Ruby
community to understand Unicode as well.

Part 1: On the Goodness of Unicode -
http://www.tbray.org/ongoing/When/200x/2003/04/06/Unicode
Part 2: On Character Strings -
http://www.tbray.org/ongoing/When/200x/2003/04/13/Strings
Part 3: Characters vs. Bytes -
http://www.tbray.org/ongoing/When/200x/2003/04/26/UTF
Part 4: Programming Languages and Text -
http://www.tbray.org/ongoing/When/200x/2003/04/30/JavaStrings

And while not directly related, Tim also fiddled with a
fully-unicode-supporting UTF-8 string class in Java with many of the typical
C string operations (strcpy, strstr, ...). Some of the logic he uses for his
byte-vector-as-unicode-string might be applicable to Ruby as well:

Excellent!  I'm particularly interested to learn more about pros/cons  
between using UTF-16 internally for all strings (Java) vs. being able  
to specify different encoding for each string object (Ruby 2.0).

Thanks for sharing,

And it's probably worth mentioning that O'Reilly has a 678 page book on
Unicode coming to bookstores by the end of the month:

HTH,
