![]() ![]() Python 3000 will prohibit encoding of bytes, according to PEP 3137: "encoding always takes a Unicode string and returns a bytes sequence, and decoding always takes a bytes sequence and returns a Unicode string". UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 0: ordinal not in range(128) UTF-8 encoding table and Unicode characters page with code points U 0000 to U 00FF We need your support - If you like us - feel free to share. > "\xd0\x91".encode("utf-8") # Unexpected argument type. > "a".encode("utf-8") # Unexpected argument type. As of Python2.5, this is not implemented.Īlternatively, a TypeError exception could always be thrown on receiving an str argument in encode() functions. ![]() However, a more flexible treatment of the unexpected str argument type might first validate the str argument by decoding it, then return it unmodified if the validation was successful. This is because the str result of encode() must be a legal coding-specific sequence. Unlike a similar case with UnicodeEncodeError, such a failure cannot be always avoided. Hence a decoding failure inside an encoder. It also appears that such "up-conversion" makes no assumption of str parameter's coding, choosing a default ascii decoder. Hi, I am trying to run the following code to export my tfidf-SVM pipeline into a PMML format: from sklearn2pmml import PMMLPipeline from import Splitter from s. I could not reproduce the bug in a development setup, only with some remote server with a 'rawer' configuration. It appears that on seeing an str parameter, the encode() functions "up-convert" it into unicode before converting to their own coding. As noted elsewhere, this is because nginx mime.types contains g which cannot be parsed as ASCII. ![]() The cause of it seems to be the coding-specific encode() functions that normally expect a parameter of type unicode. Paradoxically, a UnicodeDecodeError may happen when _encoding_. UnicodeDecodeError: 'utf8' codec can't decode byte 0x81 in position 0: unexpected code byte Since codings map only a limited number of str strings to unicode characters, an illegal sequence of str characters will cause the coding-specific decode() to fail.įile "encodings/utf_8.py", line 16, in decode The UnicodeDecodeError normally happens when decoding an str string from a certain coding. ![]()
