Use raw string for regex with escape sequences. Was previously a silent DeprecationWarning but with Python 3.12 it becomes a SyntaxWarning and for future Python releases it will become a SyntaxError.

Only logged on initial compile of pycache so need to delete ~/.kodi/addons/script.xbmc.lcdproc/resources/lib/__pycache__/ to (re)observe.

Thanks, good catch. Will quick-test a few things the next days (time is a bit limited right now).

SyntaxWarning confirmed after deleting pycache's, fixed by your change and didn't notice any breakage. Merging as-is, thank you very much!
