string :str-rev ( string $TEXT )

Returns a reversed version of $TEXT. Note that, if a bare (ASCII) string is passed, all the byte values are swapped, so any multiple-byte encodings will probably break spectacularly. If your text is UTF-8 encoded, consider passing it to this function using the language's utf8 type. This will make the function swap whole codepoints, instead of single bytes.
