stdlib: Add Unicode modifier t to control sequences w and W
As of the introduction of Unicode characters in atoms, the control sequences 'w' and 'W' can return non-Latin-1 characters, unless some measure is taken. This commit makes sure that '~w' and '~W' always return Latin-1 characters, or bytes, which can be output to ports or written to raw files. The Unicode translation modifier 't' is needed to return non-Latin-1 characters.
