Hi, it would be helpful to have the outputs of :version and :set.

[Konfekt]

I reproduced it with vim -i NONE -u ~/.vim/viminrc /tmp/test.eml and ~/.viminrc reading

set nocompatible
language messages en_US  " To avoid scrambled non english letters.

" Load plugin
let &rtp = '~/.vim/plugged/vim-matchup/' . ',' . &rtp
filetype plugin indent on
syntax on

" options go here
set hidden

Now :version yields

This issue could perhaps be related to , acting as a decimal separator by the Italian language locale.

This issue could perhaps be related to , acting as a decimal separator by the Italian language locale.

I agree it appears to be exactly this, however, I cannot reproduce this even using 8.0.1568, your example, and setting locale to it_IT.UTF-8.

I believe vim still uses dot for floats regardless of locale. What's :lang say? What does echo 12.34 say?

I know there is at least one relevant patch https://github.com/vim/vim/issues/7003. I am curious if newer vesions of vim behave the same way.

[Konfekt]

Thanks for the pointer. Indeed the issue disappears once LC_NUMERIC=C (instead of it_IT.UTF-8) set.

[Konfekt]

The issue is there as long as there are digits separated by. or , in the text.

[Konfekt]

That is, test.eml could read

> 1,1

to reproduce the error with LC_NUMERIC=it_IT.UTF-8.

[andymass]

Sorry I'm a little bit confused here- are you saying the contents of the file matters, that if the eml file does not contain 1,1 then it works fine? For that matter, does this only happen with eml files?

Anyway, how are you setting LC_NUMERIC=it_IT.UTF-8?

[Konfekt]

The issue disappears once LC_NUMERIC=C (instead of it_IT.UTF-8) set.

Setting LC_NUMERIC=it_IT.UTF-8, the issue appears as soon as there are digits separated by . or , in quoted parts of the eml file. For example

> 1,1

I did not check thoroughly for other file types. It does not happen by adding a . or , to markdown or text files, at least.

[Konfekt]

Anyway, how are you setting LC_NUMERIC=it_IT.UTF-8?

It is set system-wide on Opensuse 15.3, not by the user.
