我正在尝试从文件夹中的所有编码文件中删除所有重音符号..我已经成功构建了文件列表,问题是当我尝试使用unicodedata进行规范化时,我得到错误: **追溯(最近一次通话): 在__run中输入文件“/usr/lib/gedit-2/plugins/pythonconsole/console.py”,第336行 self.namespace中的exec命令 文件“”,第2行,in UnicodeDecodeError:'utf8'编解码器无法解码位置25中的字节0xf3:无效的连续字节 **
if options.remove_nonascii:
nERROR = 0
print _("# Removing all acentuation from coding files in %s") % (options.folder)

for dirpath, dirnames, filenames in os.walk(options.folder):
for filename in (f for f in filenames if f.endswith(exts)):
files.add(os.path.join(dirpath,filename))
for i in range(len(files)):
f = files.pop() ;
os.rename(f,f+'.BACK')

print "ERROR n %i - Could not remove from Line: %i" % (nERROR,i)
newLine = line
File.write(newLine)

看起来该文件可能使用cp1252编解码器进行编码:
In [18]: print('\xf3'.decode('cp1252'))
ó
unicode(line)
失败,因为unicode
正在尝试使用line
编解码器解码utf-8
,因此错误UnicodeDecodeError: 'utf8' codec can't decode...
。
您可以先尝试用cp1252解码line
,如果失败,请尝试utf-8:
if options.remove_nonascii:
nERROR = 0
print _("# Removing all acentuation from coding files in %s") % (options.folder)
exts = ('.f90', '.f', '.cpp', '.c', '.hpp', '.h', '.py'); files=set()
for dirpath, dirnames, filenames in os.walk(options.folder):
for filename in (f for f in filenames if f.endswith(exts)):
files.add(os.path.join(dirpath,filename))
for i,f in enumerate(files):
os.rename(f,f+'.BACK')
with open(f,'w') as fout:
with open(f+'.BACK','r') as fin:
for line fin:
try:
try:
line=line.decode('cp1252')
except UnicodeDecodeError:
line=line.decode('utf-8')
# If this still raises an UnicodeDecodeError, let the outer
# except block handle it
newLine = unicodedata.normalize('NFKD',line).encode('ascii','ignore')
fout.write(newLine)
except UnicodeDecodeError:
nERROR +=1
print "ERROR n %i - Could not remove from Line: %i" % (nERROR,i)
newLine = line
fout.write(newLine)
顺便说一下,
unicodedata.normalize('NFKD',line).encode('ascii','ignore')
有点危险。例如,它完全删除了u'ß'和一些引号:
In [23]: unicodedata.normalize('NFKD',u'ß').encode('ascii','ignore')
Out[23]: ''
In [24]: unicodedata.normalize('NFKD',u'‘’“”').encode('ascii','ignore')
Out[24]: ''
如果这是一个问题,请使用unidecode module:
In [25]: import unidecode
In [28]: print(unidecode.unidecode(u'‘’“”ß'))
''""ss

您可能希望在使用unicode(line)时指定编码,例如unicode(line,'utf-8')
如果您不知道,sys.getfilesystemencoding()可能是您的朋友。
