常见乱码参考

为了解乱码是如何形成的,我写了一个简单的demo程序辅助参考。
这是各种编码之间来回转乱会导致的可能乱码结果

总结下就是

原始编码 目标编码 结果
UTF-8 ASCII ‘ascii’ codec can’t decode byte 0xe9 in position 0: ordinal not in range(128)
UTF-8 GBK 闇嶆牸娌冨吂娴嬭瘯瀛﹂櫌 ceshiren.com
UTF-8 UNICODE_ESCAPE éœæ ¼æ²ƒå…¹æµ‹è¯•å­¦é™¢ ceshiren.com
GBK ASCII ‘ascii’ codec can’t decode byte 0xbb in position 0: ordinal not in range(128)
GBK UTF-8 ‘utf-8’ codec can’t decode byte 0xbb in position 0: invalid start byte
GBK UNICODE_ESCAPE »ô¸ñÎÖ×ȲâÊÔѧԺ ceshiren.com

示例代码

import pytest

from mtf.core.logger import log, log_to_file

log_to_file()


@pytest.mark.parametrize('from_encoding, to_encoding', [
    ['UTF-8', 'ASCII'],
    ['UTF-8', 'GBK'],
    ['UTF-8', 'UNICODE_ESCAPE'],
    ['GBK', 'ASCII'],
    ['GBK', 'UTF-8'],
    ['GBK', 'UNICODE_ESCAPE'],
])
def test_encoding(from_encoding, to_encoding):
    try:
        content = '霍格沃兹测试学院 ceshiren.com'
        log.debug(f'from = {from_encoding} to = {to_encoding}')
        log.debug(content.encode(from_encoding))
        log.debug(content.encode(from_encoding).decode(to_encoding))
    except Exception as e:
        log.exception(e)
