/* This is a gross hack to get broken programs running.
|
|
|
|
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
|
|
think 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 maximum number of characters used for the conversion is
|
|
MB_CUR_LEN.
|
|
|
|
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
|
|
file instead of the one in locale/mb_cur_max.c. This can either be
|
|
done by linking with this file or by using the LD_PRELOAD feature
|
|
of the dynamic linker. */
