Mark special characters

[Igor]

Hi,

I use latest vim v9.1.0429 on Windows 11.

In the file I have received I was convinced there are spaces between words, but there were some special characters and so when I tried to execute the commands in my cmd I have got very strange syntax errors. Probably some special character has been copied from Microsoft Word.

I would like to distinguish normal spaces with characters that are in vim displayed as spaces, but are some non-space characters. Is there a way to display those characters so that I will spot them as special characters?

Regards

Someone shared the following on the list a few years ago
https://groups.google.com/g/vim_use/c/FuEGojGwKCM/m/V1K8VAWWKrEJ

and since then I have it in my .vimrc even so I should probably change
it to a WinEnter autocommand.

" Highlight special white space
hi def link WhiteSpaceError Error
match WhiteSpaceError /[\x0b\x0c\u00a0\u1680\u180e\u2000-\u200a\u2028\u202f\u205f\u3000]/

Thanks,
Christian

Why WinEnter? Won't that set this much more often than necessary?
