[Ifeffit] IFEFFIT file saving issue

[Matt Newville]

Hi Shinhyo,

Again, I would ask to check that the folder you are having trouble saving
to has any non-ASCII characters. For sure, ifeffit and demeter are not
going to be able to handle folder or file names with non-ASCII characters.

Larch is slightly better at this - it can work with files with names in
non-ASCII text encodings.  To be clear, the situation with Larch is still
not ideal, especially on Windows, because
   a) the base installation folder can contain only ASCII characters, and
cannot contain any spaces (apparently this is some problem
       with other libraries or possibly some other variation on point b).
   b) the concept of "localization" on Windows machines is sort of a mess
and many libraries (at least, from Python) don't handle this very well.
For Larch, we recently had to explicitly set locale to be "simple C /
ASCII".  That sort (or should!?) mean that you can read/write files and
folders with non-ASCII characters, though I'm not certain that will work
for all character encoding sets.  It's possible this will get better with
time, but it's not something that we can solve.

For ifeffit / demeter there is simply no hope for non-ASCII text to ever be
handled.
