Clickable links in terminal doesn't handle non a-zA-Z letters

Steps to reproduce

• Open a terminal page or the bottom terminal utility pane
• type ~/Téléchargements/foobar (which stands for Downloads in french)

Current behaviour

The link isn't underlined entirely when hovering over e.g. foo, which means that when I click the link it opens chargements/foobar.

Expected behaviour

Links containing characters like é or any other character allowed to be in a path should be included in the underlined and clickable part.

This is very likely related to the use of regexes in ide-terminal.c.
