I'm working on a new data set coming from a MS SQL Server. There are columns that are NVARCHAR and a quick glance shows there are data in languages of Arabic, Chinese, etc... Can Neo4j store these values? Will I need to do any conversions or similar advice for storing this data into Neo4j?
There is nothing particular to do for storing Arabic or Chinese language. As a general rule make sure to pass all values via parameters in your queries.
Arabic is also displayed nicely in the node values in the neo4j-browser (aka RTL), I don't know for Chinese about the display.
