NLS error

[Anonymous]

We're getting an NLS error similar to what has been discussed here: https://forums.autodesk.com/t5/autocad-forum/missing-nls-file/m-p/3108108#M224521

However, there is no ANSI reference, it simply says "The NLS files required to interpret the text and symbol table names in your drawing of code page undefined can not be found or are not installed on your system". We have no way of knowing what language this is and as we are not sure what caused this issue to start or when it started happening we can't track down the language. Is there any way of solving this? Please see the message below:

What program generated the file(s) you are trying to open with this error message?
Where are the files from? Are these DXF or DWG files?

Have you seen this https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/AutoCA...

Yes, but the issue that Unicode is already deselected and that there is no ANSI reference. I don't know what language pack needs to be installed...

Filling in the details - The program is AutoCAD LT and the files are DWG format.

Best idea is that this started happening after copying in some elements from other drawings but we are unsure of when this happened.

Can you post a file showing this behaviour? Someone might be able to figure out what is happening.

Of course; here's a file with this behaviour. Hope that someone can figure it out...

Using WBLOCK to create a new file from your content seems to get rid of the issue, see attached.

Just a simple save, close and reopen solved it here. Which makes it hard to track down the original error because trying to track down possibly one item that causes the problem, I would do by deleting groups of objects and saving until the error goes away to narrow it down, but just a save after doing nothing and no more error to find 🤔

The WBLOCK method seems to have solved the problem! Thank you very much!
