Escape string conversion is incorrect

[capthehacker99]

Given the following script as test.lua:

print(("\128"):byte(1, 1) == 128)

Run darklua minify test.lua test.min.lua to get test.min.lua:

print(('\u{80}'):byte(1,1)==128)

Run both scripts using luau and observe that the first script will print true while the second one will print false

Seems to have been introduced in 0.14.1, as in 0.14.0 this doesn't seem to be an issue. (Possibly #232 ?)
