Check mintty/Options/Text/Locale[en_US]/Character set[UTF-8]/Apply/Save.
Then exit and restart mintty and your shell.

To see what locale Cygwin thinks you are set to, run:
	$ locale

To check all Windows locale settings, you can run:
	$ for o in -s -u -n -i -f ''; do locale $o; done

The first two should show your Windows install locale, the rest should show
anything you have set up, or the same locale.
If any settings don't match LANG, you may have to set LC_ALL=$LANG to force the
setting.
I use the following profile stanza across all systems for consistency:

# Set user-defined locale - use regional settings if available
locale -fU > /dev/null 2>&1     \
        && LC_ALL=`locale -fU`  \
        || LC_ALL=`locale |	\
		/bin/sed '/^LANG=\|^LC_CTYPE=\|^LC_ALL=/{s///;h};$!d;x;s/"//g'`
export LC_ALL
