Jython 2.5.1：UnicodeDecodeError

Question

最近我在尝试用Jython脚本从HTML文件中提取数据，使用的是QF-Test 3.5.4版本（注意，根据3.5.1版本的发布说明，支持的Python版本仅为2.5.1。 - http://www.qfs.de/en/qftest/relnotes.html#3.5.1）。

我使用的Python库（因为需要支持Python 2.x，所以这些库比较旧）：

html5lib 0.95
BeautifulSoup 3.2.1

我在运行Xubuntu 13.10系统。

我的Jython脚本大概是这样的：

    #Script uses obsolete Python libraries because QF-Test only supports Python 2.5.1
import urllib

#BeautifulSoup 3.2.1 - Python 2.x support
import BeautifulSoup

#html5lib 0.95 - has Python 2.5.1 support
from html5lib import sanitizer
from html5lib import treebuilders

#URL of HTML file that has been saved locally
url = 'Tlacovky/$(website)'
fp = urllib.urlopen(url)

#create HTML5 parser
parser = html5lib.HTMLParser(tree=treebuilders.getTreeBuilder("beautifulsoup"), tokenizer=sanitizer.HTMLSanitizer)
html5lib_object = parser.parse(file_pointer)
html_string = str(html5lib_object)

#load to BS
soup = BeautifulSoup(html_string)

for content in soup.findAll('script'):
    print content

现在，当我尝试运行这个脚本，并且所有需要的变量都设置正确时，我遇到了这个问题：

UnicodeDecodeError: 'unicodeescape' codec can't decode bytes in position 48-54: illegal Unicode character

我成功找到了问题的根源，出在导入“inputstream.py”这个文件上，错误就是在这里发生的。

我真的是快抓狂了。如果你能帮我解决这个问题，我将非常感激。

编辑：

通过修改inputstream.py解决了这个问题：

invalid_unicode_re = re.compile("[\u0001-\u0008\u000B\u000E-\u001F\u007F-\u009F\uD800-\uDFFF\uFDD0-\uFDEF\uFFFE\uFFFF\U0001FFFE\U0001FFFF\U0002FFFE\U0002FFFF\U0003FFFE\U0003FFFF\U0004FFFE\U0004FFFF\U0005FFFE\U0005FFFF\U0006FFFE\U0006FFFF\U0007FFFE\U0007FFFF\U0008FFFE\U0008FFFF\U0009FFFE\U0009FFFF\U000AFFFE\U000AFFFF\U000BFFFE\U000BFFFF\U000CFFFE\U000CFFFF\U000DFFFE\U000DFFFF\U000EFFFE\U000EFFFF\U000FFFFE\U000FFFFF\U0010FFFE\U0010FFFF]")

#Craziness
if len("\U0010FFFF") == 1:
            self.reportCharacterErrors = self.characterErrorsUCS4
            self.replaceCharactersRegexp = re.compile("[\uD800-\uDFFF]")
        else:
            self.reportCharacterErrors = self.characterErrorsUCS2
            self.replaceCharactersRegexp = re.compile("([\uD800-\uDBFF](?![\uDC00-\uDFFF])|(?<![\uD800-\uDBFF])[\uDC00-\uDFFF])")
