The unicode hack is in the comments. Google "Trojan Source". Having never dealt 
with Hebrew and Arabic, it was news to me there is a right to left feature in 
Unicode.

Or look for the paper. Hopefully this isn't too off topic.

Did you check yourself?

The only source code files which contain non-7-bit-ASCII characters are
1. src/lib-storage/list/mailbox-list-index-status.c
  * Opportunistic function to see ïf we can extract guid from mailbox path */

i.e. in a /* comment */, and it's 8-bit ASCII not even UTF-anything.

2. src/lib-mail/test-qp-encoder.c
which defines binary data.

I don't think any C compiler allows Unicode in the code itself (instructions,
variables names, etc.)

Cheers.
