There you go.Introducing case sensitivity into what is mostly a case-insensitive world just for the convenience of a few programmers I do not consider to be acceptable. It would cause more problems for far more people than the insignificant few who insist on using obscure character sets. Why should the English-speaking world be forced to suffer just because some minor languages cannot handle case folding?The number of people in the world who use character sets which do not have this problem far outnumber those who use character sets which do have this problem. People without this problem far outnumber the others, so it would not be a good idea to inconvenience the many just to satisfy the few.Translation: I do not use these character sets, those who do are not important.
PHP (& File systems) are best staying away from things like that.Microsoft produces case insensitive software, including file systems, because that is what users are used to. Unix was invented in a laboratory by academics who couldn't develop case insensitive software so they called it a "feature" and not a "bug".
Not attempting case folding, and similar, makes it simpler, faster & more robust (not worrying about what sort of 'i' to convert to). It only helps those who do not know what the SHIFT key is for.Why is it not possible to identify a single upper and lower case variant for every character in every character set? -- Tony Marston
