It would be nice if some common ground concerning filename encoding

Personally I do not really care about what the precise restriction is as
long as it permits a mechanical transformation to unicode.
I raised a similar issue in
http://lists.debian.org/debian-policy/2011/03/msg00212.html
In most case, 8bit chars in filename are bugs.
Hello everybody,
quick notes in random order:
- There are here and there discussions raising possible corner cases
where distributing files with a name not representable in UTF-8 might
be justified, for instance in test suites.
- Fedora's policy is: filenames that contain non-ASCII characters must be
encoded as UTF-8. Since there's no way to note which encoding the filename
is in, using the same encoding for all filenames is the best way to ensure
users can read the filenames properly. If upstream ships filenames that are
not encoded in UTF-8 you can use a utility like convmv (from the convmv
package) to convert the filename in your %install section.
- POSIX.1-2008, section 3.276 (Portable Filename Character Set), mentions:
The set of characters from which portable filenames are constructed.
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
a b c d e f g h i j k l m n o p q r s t u v w x y z
0 1 2 3 4 5 6 7 8 9 . _ -
The last three characters are the period, underscore, and hyphen
characters, respectively.

- Similar discussion also took place in #99933. I wonder about merging this
bug (#701081) and #99933.
- Is there anybody following the preparation of the FHS 3.0 or the LSB, who
could tell us if a broader guideline on name encoding for files distributed
in core directories is under discussion there ?
Altogether, I think that it would be useful to have a policy on filename
encoding.
Have a nice week-end,
