Issue 36058: Improve file decoding before re.search (original) (raw)

Spin-off from #14929, which fixed crash. From : "The default extension is .py. The default encoding for .py files is utf-8. I think that is the default for what Idle writes. So I think this should be the default encoding (explicitly given) at least for .py files. From : (but not sure about this) "Also, perhaps dialog box could have encodings field. People should be able to grep python code for any legal identifier, and this means proper decoding according to the encoding they actually use."
