That's easy: any character that has a lower- and uppercase form, and is no=
t represented as one byte in the target encoding=2E For that matter, any su=
ch character in the non-ASCII section of a single-byte encoding, since a no=
n-mbstring case insensitive flag would presumably leave everything other th=
an ASCII letters untouched=2E

So, any non-Latin script, like Greek or Cyrillic; any accented characters,=
 unless you're lucky and they're represented by ASCII-letter plus combining=
 modifier; the Turkish "i", which if I remember rightly has three forms not=
 two; and so on=2E
