utf8Casefold

Converts a string into a form that is independent of case. The result will not correspond to any particular case, but can be compared for equality or ordered with the results of calling glib.global.utf8Casefold on other strings.

Note that calling glib.global.utf8Casefold followed by glib.global.utf8Collate is only an approximation to the correct linguistic case insensitive ordering, though it is a fairly good one. Getting this exactly right would require a more sophisticated collation function that takes case sensitivity into account. GLib does not currently provide such a function.
