"ｕｋ.Ａｓｋ.ｃｏｍ"
I don't know why & how but it is not the same font even in the source code.

There is also this kind of results for Yahoo and its subdomains. But no weird font there.

It's not new.

It's a problem for some hotel companies, that own a number of brands and use sub-domains to host them. Sometimes a search for one brand will trigger sitelinks to another and that can be very confusing.

I don't see for Yahoo.com http://www.google.com/search?aq=f&hl=en&q=Yahoo.com&btnG=Search

But is a good idea to have them. Or it can have "Related Links" for every search term and assemble all the sub-domains there.

There's nothing new except for the strange Unicode characters. Searching for Yahoo, you can find things like mail.yahoo.com or games.yahoo.com.

Oh, and cross-domain shouldn't mean "that crosses different domains"? uk.ask.com is just a subdomain for ask.com.

Can you as a webmaster tell Google to always include subdomains? I have a news page/blog hosted at Blogger with my own domain like news.domain.com. I want it to be associated with www.domain.com. Now Google handle it like a separate site even if it's always in a iframe on www.domain.com

The "weird font" seems to be because the ascii characters in the hostname have been converted to unicode "fullwidth form." (See [Fullwidth] on wikipedia for an explanation.)

I can't imagine why G is doing this, though.

I saw that a couple of months ago the other way round. Actually www is also a subdomain, so its the same.

We have a conference once a year and for that we made a subdomain. If you search for the name of the conference e.g. the name of the subdomain, google shows also links to the www subdomain.

old news... have these links to other subdomains for some months now!

i first had a directory and moved it 301 to a subdomain... directory sitelink got replaced by subdomain

I remember there was a time when I search my name the search results INCLUDE a result (on the first page) that goes back to the search results. (e.g. search for "haochi" there's a result for "http://google.com/search?q=haochi")
http://googlified.com/get-back-to-haochi-when-search-haochi/

We had cross-domain links for about a month, and then we lost our sitelinks all together. No changes to the site or anything else. We have been working to get them back since. www.montehewetthomes.com is the site if anyone has ideas for us. Thanks

Ah interesting stuff – we've never seen this before – weird font and all!
