Everything is fine before update to GSX V2, why GSX V2 have this problem? At v1 GSX reading correct afcad..
Because we changed the way we read the scenery library because, with the previous method, it wasn't possible to know the layer of scenery files added with the add-on.xml method so, if you used something like the Lorby Addon Organizer to rearrange them, GSX would know their layers, so it could "read the wrong AFCAD". But this method read the scenery_addons.XML file created by the simulator and, it's much easier to detect and support Unicode when reading an .XML file. Unfortunately, this file doesn't include the scenery layer.
So, in order to FIX the chance of reading the wrong AFCAD, we had to read the add-ons.cfg file instead and, since this is not an XML, its encoding is not certain, some utilities change it, some users change it, and it's apparently affected by your user name.
So, it's not a GSX "bug", it's a result of trying to make it MORE reliable in reading the correct scenery because, in the previous version, if you (or an utility) changed the layer of sceneries installed with the add-on.xml method, it was very likely to end up reading the wrong AFCAD. Since there are not that many users using a non-Western alphabet in their user name, this hasn't come up until you reported it.
As I've said, we'll have a look at this and, in the meantime, you might be able to fix it by changing the user name.
and i have couatl problem also 
What "problem" ?
