Hi,
In Global Settings in Joomla you have to disable unicode urls...
Then, supposing you have already installed a language file for your home language, you must set that as default for the backend...
If you ONLY disable unicode urls in Global Settings, then you will have numbers (creation date/time) in your urls....
If you ALSO install the language file for your site's language AND set it as default in the backend, then your urls will be transliterated into simple latin characters...
Not sure if this is doable if the language file doesn't contain any transliteration definitions...it should, but I don;t know if this is valid for all language files...
Alternatively, you can just type the Alias you want yourself...
Now, regarding the way the Unicode Urls are copied, this is up to the browser you are using....with Opera and IE9, I get the unicode characters copied properly...with Chrome and Firefox these characters are converted into this series of characters which is the way the browser reads it...
If you are using these browsers, one way to avoid this conversion is to NOT copy the "www." part of the URL and just add it yourself when pasting/using the link/url...
