I do it with tr and sed, for creating mp3 filenames that the car
stereo doesn't barf on:

safename=$(echo "$name" | tr '[:upper:]' '[:lower:]' | \
		sed 's/ *- */_/g;s/  */_/g' | \
		sed -f /local/share/deunicode.sed | \
		sed 's/[^0-9a-z_]//g;s/__*/_/g')

deunicode.sed contains:

	s/[ß]/ss/g
	s/[æ]/ae/g
	s/[Æ]/AE/g
	s/[äáàâå]/a/g
	s/[ÄÁÀÂÅ]/A/g
	s/[çćĉ]/c/g
	s/[ÇĆĈ]/C/g
	s/[ëéèêę]/e/g
	s/[ËÉÈÊĘ]/E/g
	s/[ïíìî]/i/g
	s/[ÏÍÌÎ]/I/g
	s/[ñ]/n/g
	s/[Ñ]/N/g
	s/[öóòôø]/o/g
	s/[ÖÓÒÔØ]/O/g
	s/[ŝ]/s/g
	s/[Ŝ]/s/g
	s/[üúùûŭ]/u/g
	s/[ÜÚÙÛŬ]/U/g
	s/[ÿý]/y/g
	s/[ŸÝ]/Y/g

It's not perfect, but it's good enough for what I need (and probably
for what you need).
