MustangPeak Common Library(http://code.google.com/p/mustangpeakcommonlib/)包含以下代码,用于将方法转换为可在回调中使用的过程:

const
  AsmPopEDX = $5A;
  AsmMovEAX = $B8;
  AsmPushEAX = $50;
  AsmPushEDX = $52;
  AsmJmpShort = $E9;

type
  TStub = packed record
    PopEDX: Byte;
    MovEAX: Byte;
    SelfPointer: Pointer;
    PushEAX: Byte;
    PushEDX: Byte;
    JmpShort: Byte;
    Displacement: Integer;
  end;

{ ----------------------------------------------------------------------------- }
function CreateStub(ObjectPtr: Pointer; MethodPtr: Pointer): Pointer;
var
  Stub: ^TStub;
begin
  // Allocate memory for the stub
  // 1/10/04 Support for 64 bit, executable code must be in virtual space
  Stub := VirtualAlloc(nil, SizeOf(TStub), MEM_COMMIT, PAGE_EXECUTE_READWRITE);

在Windows 7中使用python 3.2我在IDLE中得到以下内容:

>>compile('pass', r'c:\temp\??\module1.py', 'exec')
UnicodeEncodeError: 'mbcs' codec can't encode characters in position 0--1: invalid character

任何人都可以解释为什么编译语句尝试使用mbcs转换unicode文件名？我知道sys.getfilesystemencoding在Windows中返回'mbcs',但我认为在提供unicode文件名时不会使用它.

例如:

f = open(r'c:\temp\??\module1.py') 

作品.

要进行更完整的测试,请在utf8编码文件中保存以下内容,并使用标准python.exe 3.2版运行它

# -*- coding: utf8 -*-
fname = r'c:\temp\??\module1.py'
# I do have the a file named fname but you can comment out the following two lines
f = open(fname)
print('ok')
cmp = compile('pass', fname, 'exec')
print(cmp)

输出:

ok
Traceback (most recent call last):
  File "module8.py", line 6, in <module>
    cmp = compile('pass', fname, 'exec')
UnicodeEncodeError: …
