在Windows上的Python 2中打开名称中带有重音符号的文件 [英] opening a file with an accented character in its name, in Python 2 on Windows

问题描述

在Windows的目录中，我有2个文件，两个文件的名称均带有重音符号:t1û.fn和t2ű.fn;命令提示符中的dir命令正确显示了两者:

In a directory in Windows I have 2 files, both of them with an accented character in its name: t1û.fn and t2ű.fn; The dir command in the Command Prompt shows both correctly:

S:\p>dir t*.fn
 Volume in drive S is q
 Volume Serial Number is 05A0-8823

 Directory of S:\p

2017-09-03  14:54                 4 t1û.fn
2017-09-03  14:54                 4 t2ű.fn
               2 File(s)              8 bytes
               0 Dir(s)  19,110,621,184 bytes free

屏幕截图:

但是，Python无法同时看到两个文件:

However, Python can't see both files:

S:\p>python -c "import os; print [(fn, os.path.isfile(fn)) for fn in os.listdir('.') if fn.endswith('.fn')]"
[('t1\xfb.fn', True), ('t2u.fn', False)]

似乎Python 2使用单字节API来命名文件名，因此t1û.fn中的重音字符映射到单字节\xfb，t2ű.fn中的重音字符映射到未重音ASCII单字节u.

It looks like Python 2 uses a single-byte API for filenames, thus the accented character in t1û.fn is mapped to the single byte \xfb, and the accented character in t2ű.fn is mapped to the unaccented ASCII single byte u.

在Windows 2中，如何在Windows上对文件名使用多字节API?我想在Windows的Python 2控制台版本中打开这两个文件.

How is it possible to use a multi-byte API for filenames on Windows in Python 2? I want to open both files in the console version of Python 2 on Windows.

推荐答案

使用unicode字符串:

Use a unicode string:

f1 = open(u"t1\u00fb.fn")     # t1û.fn
f2 = open(u"t2\u0171.fn")     # t2ű.fn
