Add a comma to the sheet title of a sheet in AutoCAD

I got an email with the following question:

I was Google searching for a way to add a comma to the sheet title for ADT2007. ... However I did not find any way to do such, just a comment by someone that it was impossible.
I have figured ways to add formatting code to other text fields (like capitalizing the date and doing a shortened month)…and was wondering if you knew a way to use escape characters and/or ASCII codes to include commas and other special characters in sheet tiles?

The error message can say something like Invalid characters in the name: test , with comma. The following characters are not valid: <>\/":;?*|,=`

This reply helped this user. It works in Sheet Set Manager (SSM) in AutoCAD as well as in the Project Navigator in AutoCAD Architecture (ACA) / Architectural Desktop (ADT).

Run the program CharMap.exe found in Windows Accessories>System Tools and there you can find special characters and copy them to use.

But you cannot use the real comma , but you can use something similar like ‚ that is U+201A or Alt+0130. You can enter it by holding down Alt on the keyboard and then on the right part of the keyboard enter 0130 and release Alt. Or you can copy it from the Character Map program.

Hopefully Autodesk does something about this in a future release.
