On my Mac I have the issue that when I type the pipe character | and then pressing space, often the non-break space character (unicode U+00a0) is inserted. If anyone knows how disable this “feature” drop me a note here, this is quite annoying but I did not found the reason for this behaviour.

This looks like normal space, but VS Code highlights these places. In this example, I’m working on asciidoc files where this happens quite frequently:

This is just a small tip to fix these files with the “Replace in Files” feature. Open this from the “Edit menu”, activate Use Regular Expression (.*) and search for the unicode character with regex [\xa0] and replace by space.
