ConvToLower

convert a character to lower case. (V38)

This function tests if the character specified is upper case. If it is then the lower case version of that character is returned, and if it isn't then the original character is returned.

locale

the locale to use for the conversion

character

the character to convert

char

a (possibly) converted character

This function requires a full 32-bit character be passed-in in order to support multi-byte character sets.

Prior to V46, the builtin default routine (it can be replaced by the default language driver or, since V46, by the default charset driver) did read from unallocated memory and returned random results for characters > 0xFF. Since V46, it always returns the unchanged character in this case. Prior to V46, the builtin default routine converted '×' -> '÷'.
