Decimal and percentage mark

Does anyone else have problem using a comma for decimal and percentage mark?
I live in a country where we use a comma for decimal mark, so when I have to use it for percentage mark my brain does "a click" before writing it ;)
I looked for another marks for percentage in different shorthand systems, but all they use their "s" sign.
Let it be mentioned, I don't know from where, but I wrote % as "prs".
Here in Wikipedia, a worldmap showing where comma is used as a decimal mark:
