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 The European variants are superseded by the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