I18n - how useful is wchar_t
I'm writing a program in C++. From the start, I'm keeping in mind it might be translated to other languages. I'm looking into internationalization only to be a lot more confused on the topic.
Everything I read says wchar_t is the way to go. Easy enough. However, I know wchar_t is only 2 bytes on Windows (or at least in VC++). The Unicode standard states there are 100,713 characters in there. Which is a lot more than 2 bytes can hold (up to 65536 values).
So my question is, is wchar_t really useful? Are the rest of the Unicode characters simply 'dead language' characters then? Or should I use another method for I18n?
Thanks in advance,
