private static function Ctype::convert_int_to_char_for_ctype in Lockr 7.3

Converts integers to their char versions according to normal ctype behaviour, if needed.

If an integer between -128 and 255 inclusive is provided, it is interpreted as the ASCII value of a single character (negative values have 256 added in order to allow characters in the Extended ASCII range). Any other integer is interpreted as a string containing the decimal digits of the integer.

Parameters
