It's not enough to have similar matching at the fs level, applications need to have the same functionality around, otherwise anything that indexes the fs will have false negatives before reading the files.

Now, if this needs to be taken care of at the application level, then why have this misfeature? It'd be better to have a good library for matching this that could be aware of the language and locale (or maybe multiple lang,locale pairs) instead of throwing this feature into the fs and call it a day.

Also, if some applications benefit from having insensitive matching, like things built to run on Windows/Mac, then having a wrapper that fixed the fs access with this matching library would be enough, no need to force other applications to use insensitive matching because a single one needs it.
