Invalid UTF-8 characters in result files

[Luthaf]

Running the example simulation with mpiexec -n 2 Excimontec.exe parameters_default.txt results in results0.txt looking like this:

Excimontec v1.0.0-rc.4 Results:
Calculation time elapsed is 0.0166667 minutes.
8.98174e-05 seconds have been simulated.
44426 events have been executed.

Exciton diffusion test results:
100 excitons have been created.
Exciton diffusion length is 23.3244 � 15.0653 nm.
Exciton hop distance is 1.60557 � 1.52862 nm.
Exciton lifetime is 5.35038e-10 � 4.51257e-10 s.

There are three invalid UTF-8 values, as confirmed by iconv -f UTF-8 results0.txt > /dev/null; echo $? returning iconv: results0.txt:8:36: cannot convert. These seems to be set in

Excimontec/src/main.cpp

Lines 290 to 292 in df5a37f

The file looks fine using CP-1252 encoding, so I guess that would be the one you used. Most Unix OS do not use this encoding by default, so Linux users will not see these characters.

On the other hand, nowadays UTF-8 is pretty well supported on Windows, so changing everything to UTF-8 should be fine.
