Thanks heaps.<br><br>I was myself thinking of catcode but did not try it. Another question.<br><br>If I say for eaxmple:<br><br>\catcode`\﷼=3<br><br>﷼ is equivalent to $ in Persian and say I have defined XeTeX math codes for Persian digits so that in maths mode I can have<br><br>﷼۱+۲=۳﷼<br><br>Will it have any side effects? Or in other words can several characters have the same catcode without having any side effects?<br><br /><hr />Let ninemsn property search for you. <a href='http://a.ninemsn.com.au/b.aspx?URL=http%3A%2F%2Fninemsn%2Edomain%2Ecom%2Eau%2F%3Fs%5Fcid%3DFDMedia%3ANineMSN%5FHotmail%5FTagline&_t=774152450&_r=Domain_tagline&_m=EXT' target='_new'>Need a new place to rent, share or buy?</a></body>
