Yes, also if you switch to, e.g., bold while in underline mode.
In fact, in anything which isn't printed with a single "show"
(or one of its variants) the underline gets broken.  I think
it works surprisingly well for being such a simple solution,
but I'm sure I can improve it without too much effort, and
also make it a bit more configurable (line thickness etc.).
