Changing Numerals Language in Robohelp 2015?

I have been having trouble finding a way to change the numeral language within Robohelp 2015 for an Arabic project. The problem is that we are using numbers which appear in English instead of Arabic (Hindi numerals).

Is there is anyway to resolve this from Robohelp or at least in the final output (Responsive HTML5 or WebHelp)?

Thanks a lot in advance,

Ahmad
