Try this page with Lynx 2.7.2 or above:

If you see several letters instead of a single - your promised display charset does not support this character so "7 bit approximation" is in effect. If you see any single letter which definitely far from being supposed you have a wrong lynx settings. Press 'o' for Options menu and change "Display character set". Try again if necessary.
When you are satisfied save your changes in Options menu, thanks.
