AARGH. All the eigth bits got stripped from the example text.
So, here's the bug report again, this time with MIME junk:
System name: portnoy
Type and version: SPARC/5 8.1.11 (with mkserv)
Display type: cgthree
What were you trying to do?
Use Solaris's /usr/bin/tr to translate lowercase characters
to uppercase:
/usr/bin/tr '[:lower:]' '[:upper:]' < latin1
What's wrong:
/usr/bin/tr gets into an off-by-one error when trying to POSIX-ly
convert the characters [\337-\366\370-\377] to upper case.
(That's the characters [=DF=E0=E1=E2=E3=E4=E5=E6=E7=E8=E9=EA=EB=EC=ED=EE=
=EF=F0=F1=F2=F3=F4=F5=F6=F8=F9=FA=FB=FC=FD=FE=FF].)
The bug also exists under Solaris 2.6.
Sample invocation:
% setenv LC_CTYPE iso_8859_1
% cat < latin1
@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_ (0100-0137, 0x40-0x5f=
)
`abcdefghijklmnopqrstuvwxyz{|}~ (0140-0176, 0x60-0x7e=
)

% /usr/bin/tr '[:lower:]' '[:upper:]' < latin1

=F7=D9=DA=DB=DC=DD=DE=FE=FF (0340-0377, 0XE0-0XFF)
Note especially the last line of each output.
"=E0" (0340) has been upcased into "=C1" (0301),
"=E1" (0341) has been upcased into "=C2" (0302),
and so on. Somehow we've gotten off-by-one errors.
What should have happened:
% perl5 -ne 'print uc($_)' < latin1
@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_ (0100-0137, 0X40-0X5F=
)

Please describe any relevant documentation references:
(/usr/man/man1/tr.1)
2. The next example translates all lower-case characters in
file1 to upper-case and writes the results to standard
output.
tr "[:lower:]" "[:upper:]" <file1

You can reconstruct the "latin1" file from the body message, but
if it makes thing simpler, here's a uuencoded version of it:
begin 644 latin1
