[cvsnt] Unknown expansion option 'æ'

[David Somers]

I've created a test repository and imported two vendor branches...

$ cd ~/tmp/wxWidgets-2.5.3
$ cvs import -d -ko -I! -m "load 2.5.3" prj/wxWidgets WX_WIDGETS WX_2_5_3
$ cd ~/tmp/wxWidgets-2.5.4
$ cvs import -d -ko -I! -m "load 2.5.4" prj/wxWidgets WX_WIDGETS WX_2_5_4

When I explicitly checkout a branch by tag (e.g. cvs checkout -r WX_2_53
prj/wxWidgets) all works well.

But, if I attempt to checkout the head (i.e. cvs checkout prj/wxWidgets), I
get weirdness :(

$ cvs checkout prj/wxWidgets
cvs server: Updating prj/wxWidgets
U prj/wxWidgets/.cvsignore
U prj/wxWidgets/BuildCVS.txt
cvs server: Unknown expansion option 'æ'.
cvs server: invalid RCS expansion flags
Valid flags are one of:
t       Text file (default)
b       Binary file (merges not allowed).
B       Binary file using binary deltas (merges not allowed).
u       Unicode (UCS-2) file with BOM.
{encoding}      Extended encoding type
Followed by any of:
c       Force reserved edit.
x       Force exclusive edit.
k       Substitute keyword.
v       Substiture value.
l       Generate lockers name.
L       Generate Unix style line endings on checkout.
D       Generate DOS style line endings on checkout.
M       Generate MAC style line endings on checkout.
o       Don't change keywords.
z       Compress deltas within RCS files.
(Specify the --help global option for a list of other help options)

If I take a look at the log one of the files that's changed, then:

$ cvs log prj/wxWidgets/acinclude.m4

The kopt looks very, very, wrong when revision 1.1.1.2 happened (although it
was fine in the previous revision).

Any ideas what's going on? Both client and server are on 2.5.01.1976 and
running in a gnu/linux environment.
