Although the character directionality and composition works fine, when writing paragraphs with visual-line-mode on the lines get inverted, i.e., the line ZYX CBA appears as ZYX CBA instead of CBA ZYX The section "22.20 Bidirectional Editing" of the Emacs manual suggests forcing the directionality of the paragraph with RIGHT-TO-LEFT MARK, but this does not seem to work: even with such a character beginning the line, (current-bidi-paragraph-direction) returns "left-to-right". The RTL MARK seems to work just fine in tables. When written in a clean text-mode buffer the same text appears with proper directionality. However switching from org-mode to text-mode does not correct directionality in said paragraphs. The issue persists even when visiting the file with emacs -Q. org-version 8.0.3, same issue with v. 7.9.4 Your help is much appreciated. -- Manuel GJT [-- Attachment #2: Type: text/html, Size: 1113 bytes --] ^ permalink raw reply [flat|nested] 6+ messages in thread

This happens to me even without my .emacs loaded. I'm running Ubuntu 12.04 with m17n-(db/contrib), libm17n-(0/dev) installed. It seems that in org mode is forcing LTR in mixed-directionality texts since, for example, a heading with RTL text will not change the stars to be right-aligned, and the cursor's behavior in org mode is different than in a clean buffer. Perhaps you could show me how to ignore any previous paragraph settings other than with R-T-L MARK?

This bug seems to have nothing to do with org mode, but happens e.g. in text mode and fundamental mode as well. You should raise this issue on the emacs-list or file a bug with emacs.

I found in org.el the line 5308 (setq bidi-paragraph-direction 'left-to-right) However, bidi-paragraph-direction is always buffer local when set. That explains why switching to other mode does not help. The solution is to set bidi-paragraph-direction to nil in org buffers with mixed LTR and RTL texts. This, however, might change the alignment of some headings to right-aligned. But the bidi markers now work just fine, so it's just a matter of placing them wisely. I appreciate the time you took for this little discussion. It helped me get a clearer picture of the inner workings of bidi and emacs.
