Anyone who knows how this could be made possible? I suppose I need a locale facet like the std::ctype, but which works for UTF-8, and not just for ASCII a-z,A-Z. I guess the information in a table like this (http://www.unicode.org/Public/UNIDATA/CaseFolding.txt) could be used.
This might not work out-of-the-box. StringAlgo lib is designed around the sequences od characters. Since UTF-8 have variable character with encoding, algotrithms in the library would not work as expected. To make it working, you will need a container with iterators, that will iterate over meta-characters, not bytes.
If it's better/easier just to convert the string to UTF-32 before doing case insensitive compares, replaces I could live with that.
If you meant UTS-32 and you have a corresponding locale implementation, than this approach is a viable solution. Best regards, Pavol.
