What would you think of an iterator based approach with the following interface:
Iterators are good.
// Bideirectional iterator for UTF8 / UTF16 coded data // I: Raw data iterator // C: Unicode character type template <class I, typename C> class unicode_iterator;
Fair enough.
// I: Unicode character iterator template <typename I> class unicode_string;
Judging from the code below, this would mean that the iterator implicitly specifies the internal string type? Something like typename iterator_traits<I>::container_type cont; ?
// some standard types: typedef unicode_iterator<std::string::iterator, wchar_t> utf8_iterator;
You can't assume wchar_t is UTF-32. You can't even assume it's 32 bits.
typedef unicode_iterator<std::basic_string<short>::iterator, wchar_t> utf16_iterator;
You can't assume short is 16-bits (but that's more or less academic).
typedef std::wstring::iterator utf32_iterator;
Same.
