Hi! I have table for saving document with name.  Usually  using tajik fonts (қҳҷғӣӯ) for name document. But have problem when I insert tajik font into table it’s show sign(????) instead tajik font.  For example:

Id	NameDoc
1	Ҳуҷҷати тоҷикӣ
2	Қарорҳо

Select id, NameDoc from DocTable

Output result:

Id	NameDoc
1	Ҳуҷҷати тоҷикӣ
2	Қарорҳо

Hi PRA,

I think you need to use NVARCHAR data type for column name NameDoc  to store the various languages text characters.

Refer below link for your reference .

Insert Hindi, Marathi, Gujarati, Urdu, Persian, Arabic, Tamil and Telugu languages Text characters in SQL Server using C# and VB.Net

I used this, but not solved

Hi PRA,

I checked by checking for same text font as you posted with question also did one sample code which work fine and data get saved for typed font text. Please check the below test sample how it work for your refrence.
