Understanding character sets in software
Pieces in the character set puzzle
CHAPTER 9
To answer the question...
How are characters represented in
software, and Adaptive Server IQ in
particular?
What collations does Adaptive Server
IQ provide?
How do I ensure that error and
informational messages sent from the
database server to client applications
are sent in the proper language and
character set for my application?
I have a different character set on client
machines from that in use in the
database. How can I get characters to be
exchanged properly between client and
server?
What character sets can I use for
connection strings?
How do I create a collation that is
different from the supplied ones?
This section provides general information about software issues related to
international languages and character sets.
There are several distinct aspects to character storage and display by computer
software:
•
Each piece of software works with a character set. A character set is a set
of symbols, including letters, digits, spaces and other symbols.
•
To handle these characters, each piece of software employs a character set
encoding, in which each character is mapped onto one or more bytes of
information, typically represented as hexadecimal numbers. This
encoding is also called a code page.
