Some programs, like mailers and web browsers, must be able to convert
|
|
between a given text encoding and the user's encoding. Other programs
|
|
internally store strings in Unicode, to facilitate internal processing,
|
|
and need to convert between internal string representation (Unicode)
|
|
and external string representation (a traditional encoding) when they
|
|
are doing I/O. GNU libiconv is a conversion library for both kinds of
|
|
applications.
