transaction-comments on blockchain.info

[AvL42]

I've been playing around a bit with comments on transactions on blockchain.info.
I've also skimmed the thread about blockchain.info, but due to my newbie-state
cannot post there, yet, so I'm asking here:

What character encoding is used to store these comments? I've been trying
a few non-ascii characters (äöüßµ αβγμ ...), and most, but not all of them
turned into questionmarks.  Now I'd like to know, if these question-marks are
merely a bug with displaying the characters on the tx-pages, or if the question-
marks are already stored in the DB(*).

*: from skimming the blockchain-thread https://bitcointalk.org/index.php?topic=40264.0
I gathered, that these comments are (at least currently) *not* stored within the
actual blockchain.

Just for clarification (as I had asked for an ability to provide comments on blockchain.info a long time ago) exactly how can you enter a comment for a tx (or is this just for a tx in your own wallet)?

You can specify a comment when you create the transaction (in "Custom" mode).
I'm not aware of any way to add a comment afterwards (short of cracking the
blockchain-website just to insert the comments into their DB. ;-)

Okay - thanks for the clarification (still hoping that feature will be added provided you can prove you own at least one of the inputs in the tx).
