cant name the page_alias in my language with the babel module

[nisan]

i insalled babel module (following the new cmsmadesimple book).
when i try to name the page alias in hebrew (im from israel and hebrew is my language)
its says that "Alias must be all letters and numbers", if i name it the same name lets say "home" its says "The supplied "Page Alias" is already in use on another page. Change the "Page Alias" to something else."


now  i know that there is a page_alias that call "home"  becauz there is home page for the english section already.
what am i doing  wrong?

All letters in url are allowed just couple of month. Add feature request to allow all letters in url or at least encoded  aliases e.g. 'home' = 'בית' = '%d7%91%d7%99%d7%aa' (allow '%' in alias). For now you have to deal with [a-z,A-Z,0-9,_,-].
