ZPL ^FH command doesn't match the right UTF-8 code.

^XA

^A0N90,43^FH^FD_c2_a1

^FS

^XZ

The above ZPL command prints "í" ( small letter i with Acute). But the correct one is "¡" (inverted exclamation) as per the UTF-8 code  "c2a1". It happens with most of other characters.

I would like to print the character "ó" (small letter o with acute). The UTF-8 code for this character is "c3b3". when I use the above utf-8 character code. The printer doesn't print anything at all.

Please let me know what is the Encoding technique that ZPL use to print spanish or special characters.
