Do you know in what encoding the pathnames are _expected_ to be
stored in zip archives?

re-encoding to latin1 does not always work and may break double byte
totally (e.g. chinese or japanese).

PKZIP APPNOTE seems to be the zip standard and it specifies a utf-8
A.  Local file header:
general purpose bit flag: (2 bytes)
Bit 11: Language encoding flag (EFS).  If this bit is
set, the filename and comment fields for this file
must be encoded using UTF-8. (see APPENDIX D)

Yes, that's one of the two methods for supporting UTF-8 filenames described there.

The other method involves writing extra ZIP header fields and was invented by Info-ZIP. They don't use it consistently anymore, though (from zip -h2):

 "Zip now stores UTF-8 in entry path and comment fields on systems
  where UTF-8 char set is default, such as most modern Unix, and
  and on other systems in new extra fields with escaped versions in
  entry path and comment fields for backward compatibility."
