Documentation:
*Non-nil means graphical emphasis is displayed.

A few typesetting features are indicated in ASCII text with
certain characters. If your terminal supports it, MH-E can render
these typesetting directives naturally if this option is turned
on, which it is by default. For example, _underline_ will be
underlined, *bold* will appear in bold, /italics/ will appear in
italics, and so on. See the option `gnus-emphasis-alist' for the
whole list.

This option is disabled if the option `mh-decode-mime-flag' is
turned off.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 7.0 of the MH-E package that is part of Emacs 22.1.
