.NET Forum / Languages / C# / September 2007C$ and Chinese characters
I believe that C# uses Unicode by default for string characters. Does that mean that double-byte langauges such as Chinese can be used without doing anything special... including DB persistance? I.e., are all characters automatically double-byte? >I believe that C# uses Unicode by default for string characters.

Yes. char and string are Unicode. Just make sure appropriate fonts are installed on your computer so you can see them. > I believe that C# uses Unicode by default for string characters.

C# internally uses Unicode. When it comes to using database you will need to make sure it is all done in Unicode (how depends on the database). Arne We will be using SQL Server 2005. >> I believe that C# uses Unicode by default for string characters.

NVARCHAR/NCHAR/NTEXT as data types and teh SqlClient that comes with .NET and I think you will be all set. Arne > I believe that C# uses Unicode by default for string characters.

Just to make sure there is no confusion about the double bytes: If you mean double byte as in codepage 950: you will have to make sure you work in C# with Unicode and not with 950. If you have for example files in 950 which you need to convert, you will have to convert your files before you use them in C#. You can do this easily by using the StreamReader class with the constructor that specifies the encoding of your files. Unicode is double byte, but it doesn't mean that there is no need for a conversion when using an older double byte system > Just make sure appropriate fonts are installed on your computer so you can see them. If you work with Unicode, a standard Unicode font will do. The correct fonts problem is actually a pre-Unicode problem. You needed for example a CE font to display, for example, Hungarian because the 1250 (Central Europe) en 1252 (Western Europe) code pages have different code points: with a regular font, the 1250 code points would be mapped wrongly onto 1252 glyphs contained in the regular font This will be a new application so will not involve any conversion. Sounds like we will be OK. >> I believe that C# uses Unicode by default for string characters.
