problem comes from the test cases made by go "utf8" TLE.encodeUtf8 TLE.decodeUtf8 CT.utf8 in the test suite

and the error is coming from TLE.decodeUtf8, not the conduit-extras code

So conduit-extra's CT.utf8 is succeeding while TLE.decodeUtf8 is failing.

The \xc2 is pretty consistent. This StackOverflow post. Calling TLE.decodeUtf8 pretty consistently fails with `"\xc2".

Building conduit-extra with text-1.2.5.0 and I cannot trigger the bug. That makes me suspect the implementation of Data.Streaming.Text.decodeUtf8

Seems to be related to this: fpco/streaming-commons#70

The seemingly related issue fpco/streaming-commons#70 was fixed in fpco/streaming-commons#71. Does that mean that this issue is fixed as well?

The PR does refer to a flaky test, but I don't know if it's this one.

Could this be related to

? Because I see mentions of UTF8 above.

Yeah, [194] (aka [0xc2]) is supposed to fail to decode that way.

We can also write this byte as 0b11000010, which makes it more obvious that it has the form of a leading byte for a 2-byte sequence, but there is no trailing 0b10xxxxxx byte, so it's impossible to decode correctly. It appears that conduit-extra's UTF-8 decoder is NOT failing when it should.

@SamB I am not sure whether you are implying that conduit-extra has UTF-8 decoding separate from the text package? If the issue was fixed in text-2.0.2, does that also fix the issue with conduit-extra?
