Subject: [Idle-dev] [BUG]: Can not save anything on IDLE since v3.8.4!!
Message-ID: <HK0PR01MB18927CDBC251EFC6D28BA263FB790@HK0PR01MB1892.apcprd01.prod.exchangelabs.com>

Hello,

I created a new py file that can be saved and run on IDLE v3.8.3.
I also created a new py file on IDLE v3.8.4 but it can NOT be saved!
Tried to edited an old version(e.g. v3.8.3) created py file on IDLE v3.8.4 , it can be saved! That's so strange!

It still cannot save on current latest version v3.8.5!! I tested this function both on 32-bits and 64-bits and they are all CANNOT work!!

Please check and fix this bug ASAP!

Regards,
Eason

The specific bug in 3.8.4 is not saving files with non-ascii characters. 
  Either put 'import io' at the top of <python-dir>/Lib/idlelib/iomenu.py
or install 3.8.5, which has the fix.

I just saved and ran
print('eyes ?? snakes ?')
Note that the snake emoji is not in the Basic Multilingual Plane and 
such characters are not officially supported by the tcl/tk gui 
framework.  They mess up editing a bit, but I put it in to test the fix.

Perhaps your system or file has another issue.  Reduce your file to the 
minimum content that has a problem.   Then copy it in a response.

Hi Terry,

Thanks for response again.

I tried to create a new file with "File => New"  on 3.8.5. It's true that can be saved as usual. I will take this advice for temporarily.

Sorry for the inconvenience as you don't know Chinese. I just used numbers, English characters and Chinese characters to test print. It's proved that whatever characters are all cannot be saved.

As you mentioned that this fix will be released on 3.9.0 or later version, isn't it ?

Regards,
Eason
