I don't understand this part.  Eli listed the following capabilities:

* bold, italics, and other important face attributes
* Some characters are not covered by fixed-pitch fonts, so they cannot be displayed. The usual box-with-hex-code display of such characters will also be lost, so we will be left with displaying them as ? or somesuch.
* Character composition will also be lost, so bye-bye prettify-symbols-mode and support for some scripts that cannot be displayed without composed characters.
* Some characters (mostly from East-Asian scripts) need to be displayed at twice the width, so either you give up those scripts, or you are back to the original problem.

Many (all?) of these features are available in the terminal, too (at least the following: bold, underline, italics, characters that don't have fixed-pitched fonts, prettify-symbols-mode, and wide characters).  What did you mean by "terminal Emacs doesn't have those capabilities in the first place"?

Clément.
