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.
