Hi,
here is an unicode regex example, which I want to get matched:
#include <iostream>
#include
#include
int main()
{
std::setlocale(LC_ALL, "");
boost::wregex condition(L"\\p{u}");
std::wstring test_word(L"Ü");
if (boost::regex_match(test_word, condition)) {
std::wcout << L"Matches!" << std::endl;
}
boost::wregex condition2(L"[[:upper:]]");
if (boost::regex_match(test_word, condition2)) {
std::wcout << L"Matches!" << std::endl;
}
boost::u32regex condition3 = boost::make_u32regex(L"\\p{u}");
if (boost::u32regex_match(test_word, condition3)) {
std::wcout << L"Matches using lib icu!" << std::endl;
}
return 0;
}
Compiled with -lboost_regex -licuuc.
Result: Only the last regex condition matches.
So I have a few questions:
1. Is u32regex + make_u32regex the *only* way to get my regex condition
matched?
2. Why does "upper class" in the second regex condition not match. E.g.
when I use:
echo "Ü" | grep '[[:upper:]]'
on command line - it works properly :)
Thanks in advance + regards,
Stefan
