It seems to me like Boost.Regex is much more powerful than QRegExp of QT. Can Boost.Regex work with QChar [1] as charT? The text "i.e. either char or wchar_t" on [2] made me unsure of this. Any limitations I should know about? Thanks for your help! Sebastian [1] http://doc.trolltech.com/4.3/qchar.html [2] http://www.boost.org/libs/regex/doc/basic_regex.html
