The use of the "name" tag across Algeria

hi
I’m whith hiddeneyes02

look here
you can see that the language used in the West Bank (and all the Middle East) is Arabic, and the other side is the Hebrew.
and all the Globe is an example
Russia in Russian
china in Chinese
portugale in Portuguese.
etc …
In short OSM is a database, you can get what you want, if you use the appropriate quiry via web, apps or software.
ex: http://mlm.jochentopf.com/
or osmand

and about the multi language it causes display problems in some PC configuration and application.
