[XeTeX] numbering parameters in XeTeX

[وفا خلیقی، Vafa Khalighi]

Hello

Is it possible to use Persian numbers for numbering parameters in XeTeX and if not, can this be done in the macro level?

For example this is the minimal test file in  Plain TeX file that I tried

%%%%%%%%%%%%%%%%%%%%%%


\def\name#۱{\begingroup\bf#۱\endgroup}
test
\end%%%%%%%%%%%%%%%%%%%%%%

so I have written 1 in Persian and this is the error I get:

%%%%%%%%%%%%%%%%%%%%%%%%%%


! Parameters must be numbered consecutively.
<to be read again> 
                   ۱
l.1 \def\name#۱
                {\begingroup\bf#۱\endgroup}
? %%%%%%%%%%%%%%%%%%%%%%%%%%%
