UnFormat.lsp does not work in Autocad 2021

See if this works.

I have put the other routines as sub routines (LM:Unformat and DoUnformatTable).

Changed the text modifying about so it uses entmod instead of vla (personal preference)

Try it and see if it works - if it does then the unformat part (Lee Macs) is working as expected (it usually does) and there is something you'll be wanting to look at in the code you added.

@Steven P thanks.

I ran your code, but unfortunately the mtexts were deleted again.

This is an interesting topic.

I edited my code to recursively search any file loaded with 'load' at all nesting levels. Try it.

I've modified the code so that it also analyzes the files loaded from the profile.

If after trying this nothing different comes out, then the problem isn't due to overlapping code.

In that case, I would look at the system variables and any reactors your LISPs generate when loading.

However, reviewing your explanation of the problem, I checked the MTEXT entity lists and saw that it forces the font to change to ISOCTEUR or SIMPLEX. I don't think these fonts support Cyrillic. Perhaps for this reason, when trying to replace the codes, it returns an empty string, which AutoCAD interprets as deleting the MTEXT.

There is no problem with fonts.
I can't understand why this UNFORMAT.lsp works for me in Autocad 2019, but not in Autocad 2021.
I have another code that works in Autocad 2021, but it has slightly fewer functions.

Try this, taking away the text modification part:

It should put the original text + format codes one one command line, and the next unformatted, see if it gets that far. It won't change any of the drawing.

The following text is output to the command line:

@GLAVCVS Maybe you're right about the fonts. If you replace the font in the text editor with Standard or Arial, the text will remain without control codes.

2025-08-18T08:52:29Z

Just a thought then, has the text gone really really small so you cannot see it at that zoom level? Some fonts when you change them do that.

"select"

"all"

should find them if they are like that

@Steven PYour assumption is correct.However, it is not possible to highlight the text using a frame.
You can only use the keyboard shortcut ctrl A.
But the content of the texts is not displayed in the properties...

This means that the texts are not deleted, but are transformed into empty text objects.

If you call the Purge command, the "Delete empty texts" function becomes active.

Did you reset AutoCAD to defaults as I suggested a long time ago?

2025-08-18T10:39:04Z

So we can force the height to be something like this - just as an example for your sample drawings above, see if it makes your text visible again

So we can force the height to be something like this - just as an example for your sample drawings above, see if it makes your text visible again

No, empty texts again...

Did you reset AutoCAD to defaults as I suggested a long time ago? as I suggested a long time ago?

If I reset the AutoCAD settings to the default values and then add my custom settings again, will the error happen again? It doesn't seem to me to be related to user settings.
I use a lot of codes, and they all work flawlessly.
