A month ago, for 3.5 and 3.6, I added a test file by Westley Martínez (note accent on i) and then his name into Misc/NEWS and idlelib/NEWS.txt. As a result, the latter will not display when the button on About IDLE is clicked. Instead, a UnicodeDecodeError is sent to stderr. I will add a test for the About box.

[terryjreedy]

Larry, there is a slight reversion in 3.5.2rc that I think should be fixed: idlelib/NEWS.txt will not display from About IDLE dialog because it had a couple of non-ascii chars. idle_news-35.diff has the full patch. A minimal fix for 3.5.2 final would consist of changing 'ascii' to 'utf-8' in idlelib/aboutDialog.py and the recoding the 2 characters in NEWS. Testing changes in the other 2 files could wait.

Since I don't know how you want to do this now, I have not pushed anything yet.

fix idle about dialog bpo-27365

If the diff is literally changing two lines, I'll accept it. Guido relaxed the rules for IDLE changes. If it breaks something it's on *your* head ;-)

Please just check it in normally. Either I'm going to use hg to cherry-pick the changes for 3.5.2 final, or I'm going to have to apply patches manually anyway. Either way an hg checkin is fine.

Please check in this minimal change *as a separate checkin* from the larger changes, if you're committing the other changes any time soon.

[terryjreedy]

I should mention that I have separate 3.5 and 3.6 patches because I know that the merge will not work.

[terryjreedy]

I was wondering if splitting the patch would be better. Shelve makes it easy.

783dfd77e4c1 is the one to pick for 3.5, then null merge if you merge to 3.6.
