Trouble with umlauts

[calime]

Would any of you gracious people here know whether there is any way for me to actually read my DRM-d .epub files with an actual e-reader instead of a PC/laptop? The problem being that they require the credit card number and the name on card to unlock, but my name happens to contain a few pesky non-English characters - an "a" with umlauts (http://en.wikipedia.org/wiki/%C3%84).
At the moment I have an old e-reader (eSlick by Foxit, discontinued model) which never got to the software upgrade that would've included non-standard charaters. I will be buying a new e-reader soon and am looking at different ones (I'd prefer e-ink, and that it'd read .epub, .pdf, .txt, preferably .doc and .mobi as well, good battery life is a must, don't really care about WiFi).
So, to clarify the question - do you know of any e-readers that support that pesky "ä" character (for example, would Kobo Touch allow me to read my DRM-d .epubs as well as non-DRM-d ones)? Also, I would very much welcome any suggestions and comments on the topic of which e-ink reader to buy (keeping in mind that I'm in Estonia, that is European Union re: availability issues and I would really like to exhaust all other options before even looking at Kindles:) For example, a few readily available readers I've found at the moment are Sony PRS-T1, Kobo Touch, Iriver Story HD, B&N Nook.)
Thank you!

What sort of DRM is it? Can you just strip it with Apprentice Alf tools?

(ETA: I bought a Kobo Touch, but could just as easily have gone with the Sony.. I'm happy.)

It's Fictionwise secure eReader DRM - http://www.fictionwise.com/help/ereader-overview.htm
I've never heard about Apprentice Alf tools, but a quick Google tells me it's worth checking out - thank you!
(I've also eyed Kobo Touch as the best possible idea, but I've been a bit discouraged by a few negative reviews about comfort of usage)

I have the Kobo Touch and like it a lot! One nice thing is they frequently update the software and make improvements which have been suggested to them. Also, they are responsive (not fast, but they do respond) to email queries.

My Sony 650 has no problems with åäö.

Also I need to be in dw more than once a week.

Thank you! I've recently managed to acertain that Sony PRS-T1 also has all those characters available via the virtual keyboard.
Now I just need to get my hands on a Kobo Touch to check, and then I can decide...
