A problem with building CUDA sample

Installed Visual Studio 2013 with Update 4 and CUDA Toolkit 7.5, build some samples of CUDA or create new CUDA project,I will get the error:

1>C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\nvvm\bin\cicc.exe : IO error : Error opening output file ‘C:/Users/龙东之寒/AppData/Local/Temp/tmpxft_00000e90_00000000-4_kernel.ptx’: 在多字节的目标代码页中,没有此 Unicode 字符可以映射到的字符。
1> kernel.cu

How to fix it ?

nvcc does NOT support multibyte characters in temporary dir.
so, you’d better to change account, or TMP/TEMP environment var.
