I'm working with maps in Illustrator and for a long time copying and pasting text inside an illustrator document has been acting weird. Each time I paste, the text is being pasted, but also added to the text is one or a few letters from a symbol font. It's like when copying text, it also copies something else.

Today I noticed that I have one symbol which is basically one of the letters in one of my symbol fonts. (not outlined) And when outlined that symbol instead I noticed that pasting text no longer added the symbol font in the end!

So somewhere there's a major bug. Not sure if it's in your copy/paste routine or something about handling symbols.

In the video I attached I show you the process.

• First I copy a piece of text and paste it below. The symbol font is added to the end.
• Then I change the symbol being a font symbol to an outlined vector symbol.
• Another try with copying and pasting text. The extra symbol is gone!

I'm using Illustrator 2021 and MacOS 10.15.7.

This bug has been with me for at least 4 years.
