Universal Character Set-2 is an early version of Unicode that has been superseded by the Unicode UTF-16 standard

UCS-2 is limited to 65.535 characters and produces a fixed-length format by simply using the code point as the 16-bit code unit

In UCS-2 each character is represented by 16 bits or 2 bytes. (The number 2 in UCS-2 indicates 2 bytes.)

For example:

Uppercase A is represented by 0041. This encoding is no longer sufficient and has been superseded by the UTF-16 encoding.

UCS-2 was superseded by UTF-16 in version 2.0 of the Unicode standard in July 1996.

What is the maximum number of characters in an USSD message?

I've understood that an USSD message consists of 160 bytes. For 7 bit data coding schemes, the maximum number of characters is 160*8/7 which gives 182 characters. It's unclear to me what is the maximum number of characters for UCS2 encoding.…

What are the consequences of storing a C# string (UTF-16) in a SQL Server nvarchar (UCS-2) column?

It seems that SQL Server uses Unicode UCS-2, a 2-byte fixed-length character encoding, for nchar/nvarchar fields. Meanwhile, C# uses Unicode UTF-16 encoding for its strings (note: Some people don't consider UCS-2 to be Unicode, but it encodes all…

Change encoding (collation?) of SQL Server 2008 R2 to UTF-8

We'd like to move our Confluence system to a SQL Server 2008 R2. Now, since Confluence uses UTF-8 encoding, I'd need a database using the same encoding (I guess that's the collation?). There's the command alter database confluence set collation…

According to this, SQL Server 2K5 uses UCS-2 internally. It can store UTF-16 data in UCS-2 (with appropriate data types, nchar etc), however if there is a supplementary character this is stored as 2 UCS-2 characters. This brings the obvious issues…

UCS-2 and SQL Server
