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 is unexpected, you have incorrect 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.
