The "%" character is sometimes use in URL's, thus in \url as a real
character, but the LaTeX mode thinks that's beginning a comment: %
and the following characters in the line are colorized as a comment,
and } isn't seen as a closing bracket. Example:
\url{http://localhost/#foo%20bar}
/usr/share/texlive/texmf-dist/tex/latex/url/url.sty says:
% A form of \verb that allows linebreaks at certain characters or
% combinations of characters, accepts reconfiguration, and can usually
% be used in the argument to another command. It is intended for email
% addresses, hypertext links, directories/paths, etc., which normally
% have no spaces. The font may be selected using the \urlstyle command,
% and new url-like commands can be defined using \urldef.
%
% Usage: Conditions:
% \url{ } If the argument contains any "%" or "^^", or ends with
% "\", it can't be used in the argument to another command.
% The argument must not contain unbalanced braces.
% \url| | ...where "|" is any character not used in the argument and not
% "{" or a space. The same restrictions as above except that the
% argument may contain unbalanced braces.
