Hebrew in OSC Store

[Lost]

Hi,

I've been configuring an OSC store that is going to be held in Hebrew (and only in Hebrew, I've canceled the multi-lingual option). During the configuration process I have encountered some problems regarding the nature of the language:

(1) Changing the writing direction and the text-alignment in the outgoing mail to the costumers- we nee it to be "direction=rtl; text-align=right". I don't know where to modify this. Same goes for the emails sent to the store administrator by the customers (through "contact us") and for the comment boxes (in any of the checkout pages).

(2) Any Hebrew word in the "To", "From" or "Subject" fields of an email sent from the store administrator to the customer appears as XXX (one X for each Hebrew letter). Can we present Hebrew names in those fields after all, and if so, what do I need to change to do this?

Thank you in advance for any answer you might have.
