Convert throws fallback exception while converting if string has non-iso characters — Tertium. You need to fix the source of the string in the first place. It's when you take that string and convert it to a set of bytes that encoding comes into play. Lasse V. Karlsen Lasse V. Karlsen k 95 95 gold badges silver badges bronze badges. It's coming directly from App. Thank You! The encoding of that file might impact how the file gets interpreted, so I would look at that. Correct me if I'm wrong, but my understanding is that, while technically it "isn't in any particular encoding", a.
It even uses surrogates in the same way which seems like an encoding trick. Of course, you generally want to store files as UTF-8 but process the data in memory as bit. Or bit, to avoid the complexity of surrogate pairs, though I'm not sure if that's really feasible. JonCoombs I don't think that's correct. UTF works with expanding opcodes. Net strings just use an array of bit code points, without any expansion. Seems bit strange code.

The problem in the code is indeed that the author seems to assume that a String in C can already be stored "using" a certain encoding, which simply isn't true; they're always UTF16 internally. Fully agree. When you already have UTF, it is quite hard to make that into correct encoding, because when you converted byte array to string with wrong encoding there is already loss of information.
Just used the Nathan's solution and it works fine. GetString fileContent, 0, fileContent. Unicode, isobytes ; return Encoding. GetString ubytes, 0, ubytes. Length ;.

For example, I have a txt file called iso I can check its encoding using the tricks mentioned above.
Note that when using xxd , the hexadecimal presentation is shown. If not given, it defaults to a platform dependent value.
According to bultins. This should only be used in text mode. The default encoding is platform dependent, but any encoding supported by Python can be passed. See the codecs module for the list of supported encodings.
I often use the utility methods available in class java. For example, reading all lines from a txt file txt can be done as follows. Read content as bytes is possible, too. Improve this answer. Adam Rosenfield Adam Rosenfield k 95 95 gold badges silver badges bronze badges. Good point, although I would suggest that use of buffers may not always be the most convenient way.
Basic InputStream and OutputStream with appropriate wrapping Readers, Writers are sometimes more useful, and do not require the whole content to be kept in memory. But which is more convenient depends on use case of course. Anne Joachim Sauer Joachim Sauer k 55 55 gold badges silver badges bronze badges.

You will have to do something with the characters that cannot be encoded. For the problem at hand, this is the simplest and a correct solution.
One might consider using StandardCharsets. But for that case, I'd probably go with something like stackoverflow. The Overflow Blog.
