There's an explanation to be found in less' man page and Mutt's manual. <http://www.mutt.org/doc/manual/manual-2.html#ss2.3> "Also, the internal pager supports a couple other advanced features. For one, it will accept and translate the ``standard'' nroff sequences for bold and underline. These sequences are a series of either the letter, backspace (^H), the letter again for bold or the letter, backspace, ``_'' for denoting underline. ..." You can convert those sequences to regular text using col with its '-b' option. Due to some versions of col's inability to handle UTF-8, the '-p' option may be necessary as well.
