+ ISO C provides no mean to find out how many bytes the wide
+ character representation really uses. But it defines MB_CUR_LEN to
+ return the information for the multi-byte character representation.
+ Many programmers don't know the difference between the two and
+ thing this means the same. But assuming all characters have a size
+ of MB_CUR_LEN after they have been processed by `mbrtowc' is wrong.
+ Instead the maximal number of character used for the conversion is
+ MB_CURLEN.
+
+ It is known that some Motif applications have this problem. To
+ cure this one has to make sure the glibc uses the function in this
