In
coc#string#content_height
, coc uses thebreakat
option to determine where to break a line when it's too long. However, the option value is not properly escaped.For example,
set breakat=\ !@-+;:,./?
can lead torequest error on "nvim_call_function" - Vim(for):E944: Reverse range in character class
when lines need to be broken. In this case, the generatedpattern
is[ !@-+;:,./?]\zs
where@-+
is a "reverse range." The fix is to escape-
as well.
