我有一個python代碼來索引包含阿拉伯語單詞的文本文件。我在一個英文文本上測試了代碼，它運行得很好，但是當我測試阿拉伯語時，它給了我一個錯誤。

注意：文本文件以unicode編碼保存，而不是ANSI編碼。在

這是我的代碼：from whoosh import fields, index

import os.path

import csv

import codecs

from whoosh.qparser import QueryParser

# This list associates a name with each position in a row

columns = ["juza","chapter","verse","voc"]

schema = fields.Schema(juza=fields.NUMERIC,

chapter=fields.NUMERIC,

verse=fields.NUMERIC,

voc=fields.TEXT)

# Create the Whoosh index

indexname = "indexdir"

if not os.path.exists(indexname):

os.mkdir(indexname)

ix = index.create_in(indexname, schema)

# Open a writer for the index

with ix.writer() as writer:

with open("h.txt", 'r') as txtfile:

lines=txtfile.readlines()

# Read each row in the file

for i in lines:

# Create a dictionary to hold the document values for this row

doc = {}

thisline=i.split()

u=0

# Read the values for the row enumerated like

# (0, "juza"), (1, "chapter"), etc.

for w in thisline:

# Get the field name from the "columns" list

fieldname = columns[u]

u+=1

#if isinstance(w, basestring):

# w = unicode(w)

doc[fieldname] = w

# Pass the dictionary to the add_document method

writer.add_document(**doc)

with ix.searcher() as searcher:

query = QueryParser("voc", ix.schema).parse(u"???")

results = searcher.search(query)

print(len(results))

print(results[1])

那么錯誤是：

^{pr2}$

以下是文件示例：1 1 1 ????

1 1 2 ???

1 1 3 ???

1 1 4 ????
