Why does this remove all “%” lua

So I am working on this obfuscator and when I add my encoding algorithm after the first “)” it removes all “%” in the algorithm, how do I fix this?

Here is the way i do it:

newScript = newScript:gsub('%)', algorithm , 1)

I suggest reading the PIL regarding captures. The symbol % is a special character, therefore you need to escape it:

newScript = newScript:gsub('%)', algorithm:gsub('%%', '%%%%'), 1)

This replaces every % in your replacement string with %%, which will then become % when used as replacement in newScript.

The PIL even clearly says:

By the way, because of those changes, a `%´ in the replacement string
must be escaped as “%%”.
