I am working on l10n of WP for Hindi. I am running across an issue on the rendering of Calendar on the blog's index page. I guess the present logic is to pick the first letter of Days like S for Sunday. IMHO this would fail for languages like Hindi which are based on double byte characters. I guess if we can have something like Sun, Mon, Tues, or even for that matter S, M, T, W in the .pot file these can be transtlated to corresponding names in the target language.
Thanks and keep up the good work. I will upload hi.po once it is finished.
