按行读取之后按原文件编码类型解码，插入完后按UTF-8解码写入文件
以源文件为gbk为例，假设每5字符插入|
python2
with open('target','w') as f:for line open('source').readlines():
line=line.decode('gbk')
line='|'.join([line[i:min(i+5,len(line))] for i in range(0,len(line),5)])
f.write(line.encode('utf-8'))
python3
with open('target','w',encoding='utf-8') as f:for line open('source',encoding='gbk').readlines():
line=line
line='|'.join([line[i:min(i+5,len(line))] for i in range(0,len(line),5)])
f.write(line)
