Oniguruma is a regular expressions library.
The characteristics of this library is that different character encoding for every regular expression object can be specified.

Supported character encodings:

ASCII, UTF-8, UTF-16BE, UTF-16LE, UTF-32BE, UTF-32LE,
EUC-JP, EUC-TW, EUC-KR, EUC-CN,
Shift_JIS, Big5, KOI8-R, KOI8,
ISO-8859-1, ISO-8859-2, ISO-8859-3, ISO-8859-4, ISO-8859-5,
ISO-8859-6, ISO-8859-7, ISO-8859-8, ISO-8859-9, ISO-8859-10,
ISO-8859-11, ISO-8859-13, ISO-8859-14, ISO-8859-15, ISO-8859-16

There are two ways of using of it in this program.

• (1) C library (supported APIs: GNU regex, POSIX and Oniguruma native)
• (2) Built-in regular expression engine of Ruby 1.6/1.8
  In Ruby 1.9, Oniguruma is already incorporated by Kazuo Saito.

Platform:

• Unix (include Mac OS X)
• Cygwin
• Win32
