Unicode character information

val to_lower : int -> int

Converts the input letter to lowercase. Returns the input unchanged if it is no letter, or there is no lowercase equivalent.

This bases on the 1:1 lowercase transformation of letters, and ignores any transformation mapping one letter to several chars.

val to_upper : int -> int

Same for uppercase conversion

val to_title : int -> int

Same for titlecase conversion
