For storing Arabic and Chinese fonts in Sql Server, your tables want unichar support.
for that create the columns in Table and make sure that it's data type like nvarchar,ntext and nchar
by this way you can store different languages fonts in Sql Server Database.
For Ex:
CREATE TABLE MyTable(CompanyName NVARCHAR(100),Sex NCHAR(2),CompDesc NTEXT)
Now you can store Chinese and Arabic type fonts in this table.
For inserting records in Chinese or Arabic write this:
INSERT INTO
MyTable (CompanyName,Sex,CompDesc) VALUES (N'Some text in Arabic/Chinese',N'Some text in Arabic/Chinese',N'Some text in Arabic/Chinese' )
For inserting records in English write this:
INSERT INTO
MyTable (CompanyName,Sex,CompDesc) VALUES ('MCN Solutions','M','MCN Solutions is a rapidly
growing IT company focused on delivering the best and most cost-effective
solutions for Software Development.' )
By this way you can store multi language records in a single table.
