The easiest way I can think of is to build a (UTF-8) file named
itrans2unicode.table that looks like this
a => a
aa => ā
~N => ṅ
Then read that file into a hash at startup and then process the file
line by line using a regex like
$line =~ s/(.)/$table{$1}/g;
There is supposedly a full table at
http://www.aczoom.com/itrans/#itransencoding but I was unable to load
that page.

The most important skill a programmer can have is the ability to read.
