I encountered this issue while trying to bundle a file with thousands of escape sequences in it.

Reproduction Steps:

1. Create a Lua file with the following code: print("\x1f8")
2. Run DarkLua on the generated file using one of the following commands:
   • darklua --format "dense"
   • darklua --format "readable"
   • darklua minify

Observed Output:
The produced escape sequence is malformed

Expected Behavior:
Expected darklua to provide a valid escape sequence :(
