BTW, how is this actually going to work? Personally, I would be quite
happy with using an ANSI Regex Library (because it's "obviouly" going
to be quite a bit faster with all strings being essentially half the
size),
since that is mostly going to work just fine. The only problem would be
that it's not going to recognize "non-ASCII"-characters as single
characters,
but for 99% of the cases, that's going to be irrelevant ...
For the remaining 1%: Is there a specific UTF-8 aware Regex library
(which
would also solve that problem and still have "mostly" ANSI performance)
or
would one have to convert stuff to wchar_t and use the wchar_t based
library?
And can I get UTF-8 strings on Windows as well? I assume that even with
the
conversion overhead, it's probably still going to be faster to use the
(almost-)
ANSI version of the library.
