sasuw / Fix illegal characters in files recursively (OS X)

Created October 26, 2016 14:02

	When Maven outputs errors like

	error: unmappable character for encoding UTF8

	you can remove the illegal characters in Mac OS bash with this

	for f in $(find /private/tmp -name '*.java' 2>/dev/null); do iconv -f utf-8 -t utf-8 -c "$f" > "$f.new" ; mv -f "$f.new" "$f"; done

	N.B. iconv has to be installed first, e.g. using homebrew (brew install iconv)
