Codes with a hexadecimal value less than 20 16 are called "control characters". These were used in the past for teletype and pre-LAN communications protocols, and only a few have much relevance today. Of these, the (carriage) return ("CR") and the line feed ("LF"), or new line, are of particular interest.

if i write de word "CIEL3" using autohotkey with this command:
RegWrite,REG_SZ,HKEY_CURRENT_USER,Software\Prog\etc...,MetaStockSourceInfo1,CIEL3
the binary value at windows registry will be 43 00 49 00 45 00 4C 00 33 00 00 00 like this:
I have dificult to write this invisible char like 1C (FS) and my question is:
how to write the same word CIEL3 but adding this invisible char like this image:
thank's
