My user "ニッキー" no longer receives subscriptions emails, even though I have been editing the artists I'm subscribed to.

I think this is a Unicode problem. The last email I received was the 1st of June, where the first URLs was http://musicbrainz.org/user/escape(ニッキー)/subscriptions and my main account received an email with http://musicbrainz.org/user/escape(nikki)/subscriptions

Since the 2nd, ニッキー has received no emails and the first URL in my main email is http://musicbrainz.org/user/nikki/subscriptions so it seems to be linked to whatever "fixed" the escape(username) thing.
