ELinks 0.11.* do not support UTF-8 as the character set of the terminal. You can instead select an 8-bit character set that contains many of the characters you need, and enable the UTF-8 I/O option. ELinks 0.11.* do not support fullwidth characters either.
ELinks 0.12pre1 and later versions support UTF-8 and fullwidth characters. I don't think any version of ELinks yet supports right-to-left characters.
