Description Yan Vinogradov CLA 2022-01-14 04:37:15 EST 
There's already an existing feature for showing whitespace characters, such as spaces, tabs, line breaks, etc.

Unfortunately, this list does not include zero-width whitespace characters (\u200b), which can't be usually seen. If a code contains such characters, it may be hard to determine the cause.

I propose adding a new configuration option for configuring the visibility of zero-width whitespaces under the General -> Editors -> Text Editors -> Show whitespace characters -> Configure visibility. A replacement character would be \u2588.
