[bug?] error: stray '\357' in program

I'm running the latest beta of Visual Studio (1.1412.10). It may be my ignorance of the setup, but whenever I do:

File->New->File
CPP File
[edit file...]
Save as...
F7

I get:

filename.cpp:1: error: stray '\357' in program
filename.cpp:1: error: stray '\273' in program
filename.cpp:1: error: stray '\277' in program

Which I believe is a Unicode byte order mark.

My fix is to open the file in notepad++ and change the encoding to "ANSI or "UTF-8 without BOM"

Hi,

I am not sure why you are seeing some unicode chars in the file. You can also save with a different encoding in atmel studio with the "save as". In visual studio it should automatically warn you that you have unicode chars in your file and ask you if you want to switch to a different encoding.

The "new cpp file" option is part of the ide and not visual micro, so maybe it puts your name in the comments at the top which contains unicode?

Thanks

THe solution seems to be:
File->Advanced Save Options
Change encoding to US-ASCII - Codepage 20127
I think Unicode (UTF-8 without signature) - Codepage 65001 might work as well.

Still seems strange that it would save file as UTF-8 then choke on it when compiling.

Hi,

You used the generic visual studio feature to create a cpp file but arduino doesn't support all the features that some programs support. Vs attempts to be clever so if your name contains unicode then it will create a utf8 instead of ascii file.

Best to right click the project in the solution explorer and use the visual micro functions on the "Add" menu. The visual micro functions will create a .cpp and .h in the simpler format for you.

Thanks, I wasn't aware of that option.
