The Eigen source files are utf-8 encoded without any utf-8 BOM, this confuses MSVC.

For example, Eigen/src/Core/arch/CUDA/Half.h contains curly quotes, encoded as the utf-8 triple e2 80 9c. But the file has no BOM so MSVC is trying to load it using local machine code page, which doesn't work in China.

Can you add /utf-8 to the CXX flags for MSVC in your CMakeFiles.txt ?

Thanks.

I removed them. Let me know if there are other problematic symbols.

The following command :

Code: Select all

grep --color='auto' -P -n "[\x80-\xFF]" Eigen -R

tells me that the only remaining non ASCII character is "é". Hope that's fine.
