Anyone else seeing Chinese layer names?

[BenchmarkArch]

My 2018 AutoCad LT toolbar for the Layers pull down shows four Chinese characters at the end of the list. There’s also a Zona Verde one I’ve never created.  Anyone else running into this?

Does it happen in all drawings or only this one? Perhaps you can share the file for everyone to take a look?

[BenchmarkArch]

Happens in all drawings I remember to check lately, but haven’t gone hunting through every drawing on current projects.  I’d say a dozen drawing in the past month.

Not to scare you but it’s possible there’s a lisp code that’s running every time you open a dwg that’s generating these Chinese character layers

[RobDraw]

More than likely, you have introduced content with those layers.

That's a possibility, I suppose, I have several generations of legacy base
drawings combined into one base drawing that's Xref'd into model space. But
for the past 20 years, all of the firms who've worked on this facility have
been local Alaskan businesses and drafters. It's been on my laptop and SSD
drive for all but the original construction documents, dating back to the
early 2000's.

Looking at your screenshot, could it be you folks insert, copy/paste, xbind and do other actions from outside and other files that all of this is just clutter that needs to be purged and "merged" to other layers?
Or do you folks deliberately use shared layer namess like WALLS1 WALLS2 WALLS3 etc.

AND... a dumb question, why do you have 953 layers in one single DWG file?

[BenchmarkArch]

Yes, it's very cluttered. All those layers are inherited from different
operators on different layering systems and a bunch are part of the
original xref from the facility. Some of them are because there are three
separate drawings xref'd into a single model space to keep individual lease
area floor plans separate. But none of those drawings should have been out
of the city. Just seemed odd to me as to where they could have come from.

Those layers are just more clutter from other files then, Google translated those layer names as

... which seems to support my theory.

You have some serious cleanup to do. Best of luck.
