I mean, an ordinary unicode string without utf-8 packing takes 4 times the room of a base string. Since ECL is using a string buffer to read objects, then why shouldn't it pack them to the smallest representation when possible?<br>

Being illiterate, I only know ASCII, so, perhaps this isn't a problem in practice.<br><br>(Getting crufty old f2cl code to convert declarations like (simple-array character (*)) to just string is a pain, but that's my problem, not yours.)<br>
