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:

The substitution that I had in mind requires referring to characters based on
their unicode properties like script,

Thanks for confirming that I didn't make a wrong choice. Programs that claim to

Speaking as not-an-expert on Raku (née Perl6), you'd write the above
something like:

I use perl as a "slightly better sed", in particular the following commands I
just cut and paste and modify for use, for many years now, to do (multi-)file
