Python3, How To Encode This String Correctly?

disclaimer, I've already done a long research to solve that alone but most of the questions I found here concern Python 2.7 or doesn't solve my problem Let's say I've the following

Solution 1:

If you have the Unicode string "<h1>Sacr\xc3\xa9 bleu!</h1>", something has already gone wrong. Either your input is broken, or you did something wrong when processing it. For example, here, you've copied a Python 2 example into a Python 3 interpreter.

If you have your broken string because you did something wrong to get it, then you should really fix whatever it was you did wrong. If you need to convert "<h1>Sacr\xc3\xa9 bleu!</h1>" to b"<h1>Sacr\xc3\xa9 bleu!</h1>" anyway, then encode it in latin-1:

bytestring = broken_unicode.encode('latin1')
