 so if I summarize:

RE2:
+ UTF-16
- look ahead

PCRE:
- UTF-8

is the lookahead definitely a show stopper? if yes then we only have PCRE

On another hand, PCRE is quite the standard and I would be happy to have it.
On the other hand, I understood that UTF-8 <-> UTF-16 + index could be
really annoying for Qt (UTF-16)

Performance vs functionality?

Best regards,
Sylvain
