From this newsgroup's FAQ: "Only post to comp.lang.c++ if your question is about the C++ language itself." Thus I am simply correct? /Leigh

It's a fair bet you are off-topic in all the groups you have cross posted to. Why don't you pick a group for a language with built in UTF8 and regexp support (PHP?) and badger them? -- Ian Collins

At least my question is indirectly related to C++ by making a utf8string for the C++ language from the regular expression. Your question is not even indirectly related to the C++ language.

It should just be asked _elsewhere_. May I suggest comp.programming, where it seems to be on-topic. Best Kai-Uwe Bux
