https://bugs.winehq.org/show_bug.cgi?id=56515 Bug ID: 56515 Summary: Calling "wine reg ..." from python's subprocess lead UnicodeDecodeError if locale isn't us_EN.UTF-8. Product: Wine Version: 9.5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: alandms123(a)gmail.com Distribution: --- Created attachment 76271 --> https://bugs.winehq.org/attachment.cgi?id=76271 Python script as an example. Before concluding this I tested running other programs using Python's subprocess tools, "rm --help", "ls --help", "man --help", etc. All of them have it's output displayed normally in the language set by locale LANG environment variable, every non-English character gets decoded in utf-8 normally. But here it's what happens when trying run wine reg while scripting in python: Traceback (most recent call last): File "call_wine_reg_script.py", line 31, in <module> out, err = res.communicate() ^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.11/subprocess.py", line 1196, in communicate stdout = self.stdout.read() ^^^^^^^^^^^^^^^^^^ File "<frozen codecs>", line 322, in decode UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc6 in position 6: invalid continuation byte This happens because my system locale is set to use "pt_BR.UTF-8" and Wine's output is trying to output the word "Não" the "ã" gets interpreted as 0xc6 "Æ" latin-1 as utf-8 which end up in a UnicodeDecodeError. I attached the script (anyone testing will have to change the prefix path). I tried setting locale on the script, tried passing the environment variables to the Popen command, but the outcome is always the same. In the example script I used ja_JP.UTF-8, but any language that has non-English character will have the same problem. I tested with other Wine's commands like wineboot, winecfg, etc, but all of them displays English text so no problem there, if there's any other Wine's command that change it's output language based on the LANG environment variable, I think it will trigger it. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
