When installing python 3.3 under windows and checking "Compile .py files to byte code after installation" Lib/venv/scripts/nt/pydoc.py gets precompiled as well. This causes venv module to abort with "Error: 'utf-8' codec can't decode byte 0x9e in position 0: invalid start byte" while copying scripts from Lib/venv/scripts/nt since only .exe files are copied verbatim, and rest are treated as utf-8 text: http://hg.python.org/cpython/file/b20e473157b8/Lib/venv/__init__.py#l314 The solution is to add another exception to compileargs at Tools/msi/msi.py: http://hg.python.org/cpython/file/b20e473157b8/Tools/msi/msi.py#l419 This issue doesn't affect non-windows systems, since Lib/venv/scripts/posix doesn't contain .py files. |

Which file exactly causes the error? If it’s pydoc.py, it’s strange because the source is ASCII. Are you installing in a path with non-ASCII characters? |

If option to precompile python files is checked in installer, pydoc.py gets compiled into binary files Lib\venv\scripts\nt\__pycache__\pydoc.cpython33.pyc and Lib\venv\scripts\nt\__pycache__\pydoc.cpython33.pyo. |

Also current title is a bit wrong, since decoding error happens in runtime each time venv is invoked, while the source of the problem happens while byte-compiling stdlib at install time once. |

Not at all. I have installed Python into "C:\Program Files (x86)\Python33". Also made a copy into "D:\Python33" and got the same results. The problem is in file contents (pyc/pyo files are binary, utf-8 fails to decode them), not in filenames. |

I've made the msi.py change. Perhaps I should also catch the exception in the venv script-copying code? Leaving issue open for now. |
