Is it possible to do case-insensitive comparison with the tiny-utf8? about tiny-utf8 HOT 3 CLOSED

Hi there,

tiny-utf8 is a container for utf8-encoded unicode codepoints. It has no insights into the meaning of certain codepoint values.
In principle, what is necessary to compare two strings (=two codepoint values) case-insensitively is a Database of Codepoints and their relations (e.g. x is uppercase of y, and so on). I'm sorry, tiny-utf8 was not built for this task. ICU provides such a database.

However, once you have figure out how to compare two codepoints case-insensitively, you can do the following:

tiny_utf8::string str1, str2;
bool is_same = std::equal( str1.begin() , str1.end() , str2.begin() , str2.end() , []( char32_t cp1 , char32_t cp2 ){
    return codepoint_insensitive_compare( cp1 , cp2 );
} );

Good luck! Let me know, if there is something else I can help you with.
