CloudCompare 导出 ply格式点云导致的 UnicodeDecodeError: 'ascii' codec can't decode

如题今日处理点云时将.txt格式通过CloudCompare导出成.ply文件，结果用PlyData.read()读取一直报错

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/root/miniconda3/envs/deep_mls/lib/python3.7/site-packages/plyfile.py", line 395, in read
    data = PlyData._parse_header(stream)
  File "/root/miniconda3/envs/deep_mls/lib/python3.7/site-packages/plyfile.py", line 373, in _parse_header
    while parser.consume(stream.readline()):
  File "/root/miniconda3/envs/deep_mls/lib/python3.7/site-packages/plyfile.py", line 120, in consume
    line = raw_line.decode('ascii').strip()
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe4 in position 27: ordinal not in range(128)

找了全网博客都没有解决，最后发现CloudCompare导出时会在文件头部加上一段注释

就是这段信息影响了读取编码，删掉就解决了。。。。。浪费了我一个多小时
