Hey, now I realise, those symbols, how you can add in translation file.
Those are
Left Alt+Numpad codes.
Code:
\x01 = Alt + 01
\x02 = Alt + 02
\x03 = Alt + 03
\x04 = Alt + 04
\x05 = Alt + 05
\x06 = Alt + 06
\x07 = Alt + 07
...
\x0A = Alt + 010
\x0B = Alt + 011
...
\x10 = Alt + 016
Most game need first add \x01 in phrase.
"\x01\x02ASDasdasdsa"
In CSGO you can start with space
" \x02AsdaASDASd"
*edit
Too pad this method not work some SM basic translations phrase, because it usually print [SM] tag prefix what mess colors hexs.
