UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-1: ordinal not in range(128)

解決方案

加入編碼和解碼語句
ustr.encode("raw\_unicode\_escape").decode("raw\_unicode\_escape").encode("utf8") # 這裡的 utf8 根據實際資料編碼而定

如下：

# -*- coding:utf-8 -*-

import pandas as pd
import jieba
def cut_msg(ustr):
    ustr = ustr.encode("raw_unicode_escape").decode("raw_unicode_escape").encode("utf8") # 這裡的 utf8 根據實際資料編碼而定
    return " ".join(jieba.lcut(str(ustr)))

漢字編碼問題一直困擾著處理文字資料的童鞋，我也在不斷探索中，在此拋磚引玉，往路過大神指點迷津。
