It's OK for expr to report an error and exit in that case, which should be 
simple.

It's not a big deal.

char* -> char *

MB_CUR_MAX==1 -> MB_CUR_MAX == 1

mbs_logical_cspn ('hello','a') -> mbs_logical_cspn ('hello', 'a') [in a comment]

const char *_string -> const char *string

* mbui_cur_ptr (iter) -> *mbui_cur_ptr (iter)

(s+1) -> s + 1

Put */ at end of last line of comment, not at start of next.

MB_CUR_MAX>1 -> MB_CUR_MAX > 1

xmalloc ( blen + 1 ) -> xmalloc (blen + 1)

idx<pos -> idx < pos

mempcpy ( vlim -> mempcpy (vlim

d>=ofs -> d >= ofs

size_t c=0; -> size_t c = 0;

No need to use "const" on locals, unless perhaps you take their address.

Probably more instances; got tired of looking....
