This is helpful, thanks!

Since we only deal with base10 systems (AFAICT), this is just a small matter of
programming. We have the en->bn mapping for numbers stored in a file:
https://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3/languages/messages/MessagesBn.php?revision=110165&view=markup
So changing "২ + ৩" into something that parserfunctions can understand ("2 + 3"
in this case) is fairly simple. Here is an example of some code I just came up
with:
$revert = array_flip($digitTransformTable); # $revert now contains the
# flipped numeral translation
# from MessagesBn.php
$bn = "২ + ৩";
$bnTR = strtr($bn, $revert);
echo "$bnTR\n";
echo eval("return $bnTR;"), "\n";
This code prints the following:
2 + 3
5
In fact, poking around a bit, most of this functionality is built into MW and
just not used in ParserFunctions.
I'll attach a patch to fix this bug for ParserFunctions {{#expr}}, but, after
applying it on my local wiki where $wgLanguageCode = "bn", I can create a page
with the following:
{{#expr: ২ + ৩}} <br>
{{#expr: {{CURRENTYEAR}} + 10 + + ৩}}<br>
{{CURRENTYEAR}}
And it will display:
৫
২০২৫
২০১২
I *think* this would solve a great deal of the problem.
