Ruoyun Huang commented on BEAM-5627:


Valentyn is right, there are a lot of them in the tests.

 

I will take care of 
[filesystems_test.py|https://github.com/apache/beam/pull/6610/files#diff-9bc1968a10d6ef5df1a1690027a774b0]
 and 
[io/sources_test.py|https://github.com/apache/beam/pull/6610/files#diff-aa300c32e00d2cbf44349027b526271f]
 (apparently they will affect internal test, will need extra efforts anyway).

[~rakeshkumar] Did you check if there any other tests in IO module that fail 
with this error?

Rakesh FYI. 

 

Fixed this issue in a few modules while I am already fixing some other issues.

Matthias Feys commented on BEAM-5627:
-

[~rakeshkumar] & [~splovyt]: this is caused by the test that create inputs with 
`str()`, which behaves differently between Py3 and Py2. See table 
below([source|https://timothybramlett.com/Strings_Bytes_and_Unicode_in_Python_2_and_3.html]):
 
|Python 2|this string literal is called a "str" object but its stored as bytes. 
If you prefix it with "u" you get a "unicode" object which is stored as Unicode 
code points.|
|Python 3|this string literal is a "str" object that stores Unicode code points 
by default. You can prefix it with "b" to get a bytes object or use .encode.|

Adding .encode('utf-8') will resolve these issues.
