Hi, I am trying to recompile a plugin on windows with VS2015. I am able to build wireshark from the sources. But when I add my Plugin to sources I got the following error message.

2>------ Build started: Project: pds, Configuration: Debug x64 ------ 
2>  Generating plugin.c 
2>  Traceback (most recent call last): 
2>    File "C:\Development\wireshark\tools\", line 78, in <module> 
2>      contents
2>    File "C:\Python36\lib\encodings\", line 23, in decode 
2>      return codecs.charmap_decode(input,self.errors,decoding_table)[0] 
2>  UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 6233: character maps to <undefined> 2>C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppCommon.targets(171,5): error MSB6006: "cmd.exe" exited with code 1.
    ========== Build: 1 succeeded, 1 failed, 15 up-to-date, 0 skipped

What´s going wrong here, why won´t the plugin.c don´t be generated?

Is your plugin source only ASCII text? If not, is it in code page 1252, UTF-8, or some other extended ASCII?

The sourcefiles contained some not allowed 0x81 characters. After deleting them, the plugin.c has could be build.

On Windows, we compile with the flag /utf-8 that indicates all source files are encoded in UTF-8.

@grahamb: so you mean you use this command:

msbuild /utf-8 /m /p:Configuration=RelWithDebInfo Wireshark.sln

Nope, the flag is automagically added to the project files by our CMake files (along with many others).

See CMakeLists.txt around line 331.
