Hello Ajith, Tom Browder suggests taking a look at Raku (née Perl6), and I concur. While I don't know Malayalam at all, I can write the regex code below with ease:
> #all code below using the Raku REPL: > say '0123456789'.chars; 10 > say $/ if '0123456789' ~~ / \d+ /; ｢0123456789｣ > #now with Bengali digits: > say '০১২৩৪৫৬৭৮৯'.chars; 10 > say $/ if '০১২৩৪৫৬৭৮৯' ~~ / \d+ /; ｢০১২৩৪৫৬৭৮৯｣ >#now with Malayalam digits: > say '൦൧൨൩൪൫൬൭൮൯'.chars; 10 > say $/ if '൦൧൨൩൪൫൬൭൮൯' ~~ / \d+ /; ｢൦൧൨൩൪൫൬൭൮൯｣ More info here: https://www.nntp.perl.org/group/perl.perl6.users/2020/06/msg8828.html https://www.nntp.perl.org/group/perl.perl6.users/2020/06/msg8845.html HTH, Bill.
