Perry Medina finds that text that is cut and pasted into AutoCAD does not always assume the font you expected.

"To help eliminate any surprises, first paste the copied text into Notepad, then copy the text from the Notepad file into AutoCAD. This will usually strip the text of any formatting from the original source."

NOTES FROM CADALYST TIP PATROL: When you copy text out of the text editor (or anywhere) and paste it into another text object, Autodesk displays a warning. This indicates that the text you copied may have different formatting than the text where you are pasting, and the pasted text may not adopt the formatting of the existing text. This can lead to trouble when you try to change the settings in the text object. The pasted portion may not update. Text pasted into Notepad automatically loses nearly all its formatting, so this tip helps sidestep the aforementioned issues.
