float('∞') produces an error message that breaks the error message printer

[DavidHowlett]

Short Summary

I am using python 3.5 in Komodo 10 on Windows. The issue is also present in Komodo 9. In python the expression float('∞') should produce a value error.

Steps to Reproduce

Run the following in a python file in Komodo:

float('∞')

Expected results

Traceback (most recent call last): File "", line 1, in ValueError: could not convert string to float: '∞'

Actual results

Traceback (most recent call last): File "G:\reusable\junk.py", line 1, in Error in sys.excepthook: Traceback (most recent call last): File "C:\Program Files (x86)\ActiveState Komodo IDE 10\lib\support\dbgp\python3lib\dbgp\client.py", line 3961, in excepthook _print_exception(type, value, tb) File "C:\Program Files (x86)\ActiveState Komodo IDE 10\lib\support\dbgp\python3lib\dbgp\client.py", line 389, in _print_exception _print_tb(tb, limit, file) File "C:\Program Files (x86)\ActiveState Komodo IDE 10\lib\support\dbgp\python3lib\dbgp\client.py", line 366, in _print_tb if line: file.write(' %s\n' % line.strip()) File "C:\Program Files (x86)\ActiveState Komodo IDE 10\lib\support\dbgp\bin\py3_dbgp.py", line 129, in write self._origStream.write(s) File "C:\Program Files (x86)\ActiveState Komodo IDE 10\lib\support\dbgp\bin\py3_dbgp.py", line 129, in write self._origStream.write(s) File "c:\anaconda3\lib\encodings\cp1252.py", line 19, in encode return codecs.charmap_encode(input,self.errors,encoding_table)[0] UnicodeEncodeError: 'charmap' codec can't encode character '\u221e' in position 11: character maps to

Thanks for the report. It appears one of our components is assuming a latin1 encoding instead of UTF-8, despite UTF-8 being the encoding you are using in the file.

Note to self: possibly related to #1541

This bug was marked as part of the 10.1 milestone but I am using Komodo IDE 10.1.2 and the bug is still present.

Hi, I cannot reproduce this. I copied your source file text and get the following expected error in the "Debug output" pane:

  File "/path/to/support/dbgp/python3lib/dbgp/client.py", line 2445, in runMain
    self.dbg.runfile(debug_args[0], debug_args)
  File "/path/to/support/dbgp/python3lib/dbgp/client.py", line 2032, in runfile
    h_execfile(file, args, module=main, tracer=self)
  File "/path/to/support/dbgp/python3lib/dbgp/client.py", line 682, in __init__
    exec(contents, globals, locals)
  File "<string>", line 1
     ∞ = 'my string'
     ^
 SyntaxError: invalid character in identifier

[DavidHowlett]

That is unexpected. Can you replicate the fault on windows? Possibly that is the cause of the difference. I have simplified the error further, hoping to get something that will replicate. Try: "1/0#∞"

[mitchell-as]

Good point. When I have some time I will look into this on a Windows machine.
