Mercurial is complaining because the non-ASCII characters in the
pathname are not allowed unless an encoding is declared. This seems to
be a problem with either Mercurial or our installation procedure.

As a temporary workaround, you could build Sage in a directory whose
full name has only ASCII characters.

Thanks. It seems to work. I forgot those stupid french 'é' and 'è'!

I'd say it's a problem with Python.

Maybe time to upgrade to Python 3? Much improved unicode seems to be one of the major selling points...

Python works fine with non-ASCII characters -- if you declare the
encoding. I suppose you could say that needing to declare the encoding
is the problem, but then Python would have to figure out the encoding
automatically, and that way madness lies. (Although assuming UTF-8 when
it's not ASCII seems like a good start. Is that what Python 3 does?)

Someone (us? Mercurial people?) need to get an encoding line into those
source files.

I got similar problems for a long time, I just don't build Sage in folders whose names contain accents :)

Hi,

I am trying to install sage from source (since from binary it does not work), and I have a problem with mercurial-2.2.2.p0. I am working on fedora 17, on an Asus Ul-something.
 
Here is the last part of the installation:

Mercurial installed correctly, but doesn't seem to work properly.
Running 'hg log' in the directory /home/aleksandar/Téléchargements/sage-5.3/spkg/build/mercurial-2.2.2.p0 failed.

Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:

When you are done debugging, you can type "exit" to leave the subshell.

I also tried to install mercurial apart, but it is not the same version.

Thanks.

I think it's quite a challenge to get an encoding in the file *before*
the #! line.
