I’m NAV 2013 developer and my company has several branches located in many countries access one database in their own language.
In my opion, NAV 2013 is beautiful and convenient with languages in each countries and Unicode support. However, I realized that some companies cannot localize their system and use English only. I talked to my friend who works in IT Department and he said that we’ve used solution from a software company. He gave me a link https://skydrive.live.com/redir?resid=1322D544FED91559!107&authkey=!AI6BCiD–abnN8A where I got all information and try with default demo company.
Hope this information can help you and your company takes advantages as my company!
