summary: MSN handwritten message crash

### Description
The MSN protocol plugin used an incorrect character encoding when attempting to
convert handwritten messages from one encoding to another. This caused the
conversion to fail. This failure combined with an uninitialized variable can
trigger a crash. The only vulnerable versions of libpurple are 2.6.0 and 2.6.1.
### Mitigation
Use the correct character set name and initialize error to NULL.
