UnicodeDecodeError?

[jacobwilliams]

I'm seeing some sort of bug maybe. See below. Interestingly, if I run FoBiS again, the error goes away.

Compiling src/json_module.F90 serially

Hi Jacob, It is due to byte string "nightmare" of Python (I think). Can you give me a minimal example that raises the bug? Anyhow, I cannot fix it before oneweek... my first daugther is coming :-) !!

[jacobwilliams]

Congrats! Make sure you start teaching her Fortran early! I'll post the minimal example later.

[jacobwilliams]

Some sort of non-printing control characters got into my source file somehow. When I deleted them the problem goes away. Maybe it is not a big deal.

[szaghi]

Dear Jacob, thank you for the example. The next week (when my daugther come at home!) I will try to see the exotic characters raising the error. Probably, your Visual Studio is the "killer" :-) with vim you will have the control :-)

See you soon, I hope.

[jacobwilliams]

OK, I take back what I said. I'm seeing this error again, even though (I think) I have no unusual characters in the file. See the "refactor" branch here (commit 1272a40784). When I run the build.sh script (which is calling FoBiS) I see this error. I'm using Python 3.4.2.

I remember having something similar happen to me, but I don't recall the fix. If you just look up what that unicode address is you learn that its RIGHT SINGLE QUOTATION MARK, hardly exotic.

This reminds me somewhat of #47 that I reported, there gfortran gave error messages with utf8 characters, and FoBiS didn't like it at all.

[jacobwilliams]

Yes, it seems to have something to do with the error or warning messages emitted by gfortran. When I fixed the error in the code, the problem goes away (the commit after the one I referenced above).

Has this been fixed?
