How to do an accent insensitive grep? <p>Is there a way to do an accent insensitive search using grep, preferably keeping the --color option ? By this I mean <code>grep --secret-accent-insensitive-option aei</code> would match àei but also äēì and possibly æi.</p> <p>I know I can use <code>iconv -t ASCII//TRANSLIT</code> to remove accents from a text, but I don't see how I can use it to match since the text is transformed (it would work for grep -c or -l) </p>
