On Bengali WP, Category:Years still has "0" and "1":
There's some other odd things about that category that may be happening because they're using leading 0s in sortkeys: 0922 etc. Hopefully it'll look less weird when that fix goes out. Still, 0 and 1 aren't right.
On bn.wikisource, there's 0-9 as a heading, rather than the Bengali numbers ০-৯ :
