Program crashes when using signature in Hebrew

[metaman]

At first the signature occasionally appeared correctly and occasionally as gibberish, and subsequently stopped working entirely, crashing the program whenever I tried to insert it into an e-mail. Program works fine with other identities or when disabling the signature. I should note that I used the tilde character in the signature multiple times (for graphical purposes), in case that might relate to the issue.

The program also sometimes crashes when replying to an e-mail which contains Hebrew characters.
