20/* The implementation of the conversion which can be performed by this
21 module are not very sophisticated and not tuned at all. There are
22 zillions of ISO 646 derivates and supporting them all in a separate
23 module is overkill since these coded character sets are hardly ever
24 used anymore (except ANSI_X3.4-1968 == ASCII, which is compatible
25 with ISO 8859-1). The European variants are superceded by the
26 various ISO 8859-? standards and the Asian variants are embedded in
27 larger character sets. Therefore this implementation is simply
28 here to make it possible to do the conversion if it is necessary.
29 The cost in the gconv-modules file is set to `2' and therefore
30 allows one to easily provide a tuned implementation in case this
31 proofs to be necessary. */
