Hi Sudheera and Sergei, > In case of I missed some libraries, I guess you will enlighten me to study about them too. considering the requirements I didn't see Asian multi-byte support implemented in anywhere, what would we do about that.?
Do you know "oniguruma"? http://www.geocities.jp/kosako3/oniguruma/ http://en.wikipedia.org/wiki/Oniguruma Oniguruma is a regular expressions library, that supports multi-byte character sets like big5, euc-kr and shift_jis. Oniguruma is used by "mregexp". "Mregexp" is a multi-byte support regex UDF for MySQL. So, I think you can understand easily about how to use it.
