当我从远程 Hg 存储库中提取和更新变更集时，我收到以下错误消息：

UnicodeDecodeError: 'utf8' codec can't decode byte 0xc4 in position 44: invalid continuation byte

我发现有一个提交导致了错误，但它在我同事的 PC 上运行良好。我怎样才能跳过那个变更集或者有其他方法来修复我的本地仓库？

在我将 Mercurial 升级到 2.6 后，问题就解决了。我猜原因是 python 在 Windows 和其他系统上对文件名使用不同的编码：

http://wiki.python.org/moin/Python3UnicodeDecodeError

Mercurial 2.6 添加了一些代码来处理可能的 DecodeError：

try:
        path.decode('ascii') # throw exception for non-ASCII character
        return path.lower()
    except UnicodeDecodeError:
        pass
    try:
        u = path.decode('utf-8')
    except UnicodeDecodeError:
        # OS X percent-encodes any bytes that aren't valid utf-8
        s = ''
        g = ''
        l = 0
        for c in path:
            o = ord(c)
            if l and o < 128 or o >= 192:
                # we want a continuation byte, but didn't get one
                s += ''.join(["%%%02X" % ord(x) for x in g])
                g = ''
                l = 0
            if l == 0 and o < 128:
                # ascii
                s += c
            elif l == 0 and 194 <= o < 245:
                # valid leading bytes
                if o < 224:
                    l = 1
                elif o < 240:
                    l = 2
                else:
                    l = 3
                g = c
            elif l > 0 and 128 <= o < 192:
                # valid continuations
                g += c
                l -= 1
                if not l:
                    s += g
                    g = ''
            else:
                # invalid
                s += "%%%02X" % o

        # any remaining partial characters
        s += ''.join(["%%%02X" % ord(x) for x in g])
        u = s.decode('utf-8')`

在posix.py中
