UTF-8 Issue: Errors with Spanish text in gp.md

[kelvinauta]

If you enter text in Spanish that includes accents or the letter ñ, you get a parsing error in the body.
Example text with issues: párrafo (accent) característica (accent) mañana (ñ)

'{\n "error": {\n "message": "400: There was an error parsing the body",\n "type": "server_error",\n "param": null,\n "code": null\n }\n}\n'

Solution: delete all spanish characters and probably other characters wierd too
