Vimscript to replace persian/arabic digits with english ones

Question

I have a file that has so many persian/arabic digits in it. I would like to replace them with their English counterparts. How is that possible?

Answer 1

Use the following :s command for Persian and Urdu digits:

:%s/\([۰-۹]\)/\=char2nr(submatch(1))-1776/g

And the following for Arabic digits:

:%s/\([۰-۹]\)/\=char2nr(submatch(1))-1536/g
