No, you cannot assume anything about the size of the string, it is 
technically "opaque". For example
     setlocale( LC_ALL, NULL);
returns one of these:
     locale-name
     locale-name-list: locale-name1,locale-name2,…, (if different names 
for one or more categories.)
and if the locale is custom-created, this could possibly be long(?).
