The result is a copy of the {src} string with all characters which appear in {fromstr} replaced by the character in that position in the {tostr} string. Thus the first character in {fromstr} is translated into the first character in {tostr} and so on. Exactly like the unix "tr" command. This code also deals with multibyte characters properly. Returns an empty string on error. Examples: echo tr("hello there", "ht", "HT") returns "Hello THere" echo tr("", "<>", "{}") returns "{blob}" Can also be used as a |method|: GetText()->tr(from, to)
