What do you see if you run "fossil timeline -n 1" from the shell
outside of Emacs? does it show "Naiveté" as expected?  If it does,
then what you see above is a secondary and much less serious problem;
the repository is OK.

If that doesn't work, then I can only say that I tested this change
with a program other than fossil, assuming fossil uses the system
codepage.  It worked for me with that other program: any text I wrote
on the command line was received and processed by the program as I
expected.  Maybe fossil doesn't use the system codepage, in which case
it doesn't play by the rules of a Windows console program, and I don't
know what else we could do with this.  Sorry.
