Emacs' arc-mode.el currently doesn't support the Unicode Path Extra
Field extension of the ZIP format, so we can only display the file
name in the "DOS-compatible file name" field, which filters out
characters which codepage 437 couldn't encode.  That's what you see.

Patches welcome to add support for this feature.
