Search and replace from file in awk using a 16 bit text file

Hello,
Some time ago a helpful awk file was provided on the forum which I give below:
Code:
NR==FNR{A[NR]=$0;next}{for(j in A){split(A[j],P,"=");for(i=1;i<=NF;i++){if($i==P[1]){$i=P[2]}}}}1

While it works beautifully on English and Latin characters i.e. within the ASCII range of 127, the moment a character beyond 127 is provided for search and replace, the script fails
How do we modify the script to make it work for characters beyond
Code:
A-z

A short sample is provided below for the mapper
Code:
¦=ு
§=ங
¨=ி
©=ீ
ª=்
¬=இ
±=யு
²=வு
´=வூ
µ=பு
·=பூ
¹=யூ
¼=ஈ
¿=நூ
Á=ஹ
Ã=ஊ
Ä=னு
Å=நு
Æ=கு
Ç=ழு
È=ழ
É=ஐ
Ê=து
Ë=மு
Ì=டு
Í=ஆ
Î=சூ
Ï=டீ
Ð=்
Ñ=ணு
Ô=கூ
Õ=ரு

and a sample file for conversion is also provided below:
Code:

NAME
split - split a file into pieces SYNOPSIS
split [ option ... ] [ file ] DESCRIPTION
Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file. The names of the output files are xaa, xab, and so on to xzz. The options are -n n Split into n-line pieces. -l n Synonym for -n n, a nod to Unix's syntax. -e expression File divisions occur at each line that matches a regular expression; see regexp(7). Multiple -e options may appear. If a subex- pression of expression is contained in parentheses (...), the output file name is the portion of the line which matches the subex- pression. -f stem Use stem instead of x in output file names. -s suffix Append suffix to names identified under -e. -x Exclude the matched input line from the output file. -i Ignore case in option -e; force output file names (excluding the suffix) to lower case.
