At least, should use ja_JP.UTF8 instead of ja_JP.eucJP.

locale.getlocale() returns language code, encoding as tuple. The encoding is able to use for unicode decoding.

Replying to jun66j5:

locale.getlocale() returns language code, encoding as tuple. The encoding is able to use for unicode decoding.

Thanks for the suggestion, even if #10992 suggests it might be only an intermediate solution.

Regarding the calendar header constructor I've felt the old code was sub-optimal, but couldn't do better. Using a test result as index looks much more elegant indeed.

You proposed patch made me think about another possible aspect of customization: number of workdays per week. It must have felt as natural to you to set weekend == Sunday as it does to me to set it according to the two-days-weekend like done by the replaced code. Number of weekdays matters especially for ticket calendar due to different column widths. This is in CSS, hence it's not so flexible.

(In [12847]) WikiCalendarMacro: Use encoding to get proper weekday headers, refs #10992 and #10993.

Follow-up on [11557], although it might be yet another intermediate step as suggested by #10992. Thanks again to Jun Omae for the patch code and related explainations on the issue.

comment:5 Changed 4 years ago by Steffen Hoffmann

(In [12951]) WikiCalendarMacro: Switch from Python core modules calendar and locale towards using Babel by default, refs #10992 and #10993.

This is the bare minimum of changes, that don't break code, but turn Babel into an undeclared, strict requirement so far. I'll fix that later. Starting to remove class attribute variables for becoming thread-safe again.

Resolution: fixed
Status: newclosed

(In [12991]) WikiCalendarMacro: Releasing current, tested macro package as final product, closes #7639, #8175, #9718, #10991, #10992 and #10993.

Special thanks to Jun Omae for pushing development by testing and providing valuable hints in our discussion about utilizing Babel for better localization and for making macro execution thread-safe as well.
