GLib.utf8_casefold

function utf8_casefold(str: String, len: Number(gssize)): String {
    // Gjs wrapper for g_utf8_casefold()
}
  

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.utf8_casefold on other strings.

Note that calling GLib.utf8_casefold followed by GLib.utf8_collate 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.
