Checking it out now... still having some funkyness but now I'm wondering if it's due to bad installs/mods with weird localization. It's still not showing Guppycur's stuff right (unless the names should be long and string style) as well as some of the stuff from Dr's Golden Realms.
If you are using my script, then for best result you should use default unmodified localization files before running my script. Also, once you have all the localizations installed, avoid running the game through Mod loader, as it will rewrite your modified localization files again.
Some modifications simply don't use localizations on everything so some things like item names may look weird. Typically, when you check out the item in question manually in the items.xml and look up its name in localization.txt, you should find it there if it's translated. If it's not there, it means that the mod itself doesn't properly translate its name, so in that case it's not a bug of the script or the localization install process, but it's just the current status of the mod localization file itself.
I'm also using some mods from Guppycur as well as Dr's Golden Realms and while I'm not sure which mods from Guppycur you're using, I can tell you right now that Dr's Golden Realms in its latest version still doesn't have everything in its localization files, because it's a work in progress mod, so you may see some weird texts, unfinished stuff, placeholder texts, etc.
Also, just an example, if you're using vehicles overhaul from Guppy, you will probably see some car names without spaces which makes them kinda hard to read, but that's again only because they actually don't have proper translations in localization.txt file right now.
UPDATE: Actually, Guppycur's Vehicle Madness doesn't seem to have localizations at all lol
I hope this helps.
