Examples
Example 1 The library module filename
In the conversion library, /usr/lib/iconv (see iconv(3C)), the library module filename is composed of two symbolic elements separated by the percent sign (%). The first symbol specifies the code set that is being converted; the second symbol specifies the target code, that is, the code set to which the first one is being converted.
In the conversion table above, the first symbol is termed the "FROM Filename Element". The second symbol, representing the target code set, is the "TO Filename Element".
For example, the library module filename to convert from the Korean EUC code set to the Korean UTF-8 code set is
ko_KR-euc%ko_KR-UTF-8
