top: make that 'make_str_utf8' function more efficient

Browse Source 
Upon reflection, there was absolutely no justification
for that call to strlen() which was then followed by a
call to snprintf(). The latter provides this needed #.

[ also make that 'delta' value a little more visible ]
[ instead of hiding it at the end of a its code line ]
