Unexpected Glyphs appear randomly in some files

[SConaway]

Type: Bug

Have a line of JSON that resembles

        {"name":"WebAssign", "url": "https://www.cengage.com..."}

For some reason these symbols randomly appear in the editor, regardless of theme chosen.

I tried disabling extensions from Command Palette > Developer: Reload With Extensions Disabled and that didn't help.

Can you try in VS Code insiders with default settings? Is this caused by a font?

[SConaway]

It appeared regardless of font. I cannot replicate in Insiders with default settings, but it was happening in regular vscode.

Can you figure out which settings causes this?

Sorry I'm late here, but I couldn't make any progress figuring out what setting was the issue
