binlog2sql 解析日志失败 UnicodeDecodeError: 'utf-8' codec can't decode byte 0xba in position 0: invalid start byte

python35 ./binlog2sql.py -h... -P... -u... -p... -B --start-file="mysql-bin.091940" --start-position=43669051 --stop-position=65769997 > /export/logs/redo.sql

执行报错

第249行，修改block.decode为ignore模式

247     for block in reversed_blocks(fin):
248         if PY3PLUS:
249             block = block.decode("utf-8","ignore")
250         for c in reversed(block):
251             if c == '\n' and part:
252                 yield part[::-1]
253                 part = ''
254             part += c
255     if part:
256         yield part[::-1]

参考
