hi, Is there a reason why the template params for the tokenizer class are std::string? This makes it "harder" to use it with std::wstring. You have to write: tokenizer<char_separator<wchar_t>, std::wstring::const_iterator, std::wstring> tkz; ... Instead of: tokenizer<char_separator<wchar_t> > tkz; ... (i guess i'm very lazy ;) I changed the scope of the string_type typedef for the xxx_separator classes to public, and used this typedef in the tokenizer template params. Now std::wstring works like std::string for me. *** token_functions.hpp *** class char_separator/char_delimiters_separator/... { public: typedef std::basic_string<Char,Traits> string_type; ... }; *** tokenizer.hpp *** template < typename TokenizerFunc = char_delimiters_separator<char>, typename Iterator = /*std::string::const_iterator*/ TokenizerFunc::string_type::const_iterator, typename Type = /*std::string*/ TokenizerFunc::string_type

class tokenizer {...}; regards /dave
