Its funny you should mention that because I was thinking about that after handling this request
It made me realize that this feature is not currently localizable.
I'm not really sure of a great way to implement it, even the english implementation is not the prettiest thing though its not complicated either.
Currently it builds those links from calling this method in SiteUtils
public static string GetAlphaPagerLinks(string pageUrl, int pageNumber, string selectedLetter)
I'm thinking we could move the guts of this method into GetAlphaPagerLink_en(...)
and put a switch on CultureInfo.CurrentCulture in the GetAlphaPagerLinks method and then call language specific implementations based on the current culture and just fall back to english or make it the default when there is no method implemented for the culture.
If I do that can you implement it for your language and maybe I can ask Alexander to do it for Russian?
Of course if you have any ideas of a different way to do it I'm open to hear that too.
