Ok, great! > Moreover, if QString guarantees that it always contains a valid UTF16 string, > you can pass PCRE_NO_UTF8_CHECK all the time (just check that the starting > offset also points to a beginning of a valid UTF16 character.

Unfortunately that's not the case: from this point of view, QString is a "mere" container of UTF16 code units. One has access to the underlying data and can easily build an illegal UTF16 sequence. :-( > Btw, I heard that Qt5 alpha is released and contains a PCRE based > QRegularExpression. Really nice job! Thank you very much! Another one for the list on the homepage ;-) Cheers, -- Giuseppe D'Angelo -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
