Oniguruma (鬼車) is a BSD licensed regular expression library which supports Unicode characters in encodings such as UTF-8, UTF-16 and EUC-JP. It allows encoding to be specified for each regular expression object.

The Ruby programming language, since version 1.9, as well as PHP's multi-byte string module (since PHP5), use Oniguruma as their regular expression engine. It is usable in C/C++ and ports to Cocoa, Java and Erlang have also been made.

The current version is 5.9.4 (c) K.Kosako, updated at: 2013/04/04
