rtrim - Strip whitespace (or other characters) from the end of a string.
rtrim(str,charlist)
Optionally, the stripped characters can also be specified using the charlist parameter. Simply list all characters that you want to be stripped. With .. you can specify a range of characters.
This function returns a string with whitespace stripped from the end of str. Without the second parameter, rtrim() will strip these characters:
Make sure the locale is set correctly before using rtrim. A bad locale might produce a crash.
Note: In the followings examples, the _ between the { should be removed to make it work.
in: res={_{rtrim(charlist:"ò0..9","òóaaaÓ098")}}. out: res=òóaaaÓ.
