EXAMPLES

In the conversion library, /usr/lib/iconv (see iconv (3)),the library module file name 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

NOTES

ISO 8859 character sets using Latin alphabetic characters are distinguished as follows:
ISO 8859-1 (Latin 1)
For most West European languages, including:
               Albanian    Finnish     Italian
               Catalan     French      Norwegian
               Danish      German      Portuguese
               Dutch       Galician    Spanish
               English     Irish       Swedish
               Faeroese    Icelandic

ISO 8859-2 (Latin 2)
For most Latin-written Slavic and Central European languages:
               Czech         Polish       Slovak
               German        Rumanian     Slovene
               Hungarian     Croatian

ISO 8859-3 (Latin 3)
Popularly used for Esperanto, Galician, Maltese, and Turkish.
ISO 8859-4 (Latin 4)
Introduces letters for Estonian, Latvian, and Lithuanian. It is an incomplete predecessor of ISO 8859-10 (Latin 6).
ISO 8859-9 (Latin 5)
Replaces the rarely needed Icelandic letters in ISO 8859-1 (Latin 1) with the Turkish ones.
ISO 8859-10 (Latin 6)
Adds the last Inuit (Greenlandic) and Sami (Lappish) letters that were not included in ISO 8859-4 (Latin 4) to complete coverage of the Nordic area.
