If you go to the compose window, and select Insert -> Characters and Symbols then you'll find that the drop-down boxes have no symbols in them.
This appears to be a regression in 7.
A quick look at the error console reveals:
Error: malformed Unicode character escape sequence
Source File: chrome://editor/content/EdInsertChars.js
Line: 416, Column: 2
The "\u22d" bit seems to be the error - even my emacs picks that up as wrong. My guess is that something has got a bit stricter in 7, causing this to now be an error.

Does this mean this will be fixed in the upcoming 7.0.1 release?
Verified fixed Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0.1) Gecko/20110929 Thunderbird/7.0.1 (thus the answer to comment #5 is yes).
Note that SeaMonkey 2.4.1 didn't pick up that fix (spun too early).
