Sun 02 Apr 2017 09:54:53 PM UTC, comment #4: What about displaying '<' for the left half of a double-width character and '>' for the right in display_string()? This would be clearer than putting blank spaces before the "$" token. (Obviously, doing this is much more useful in non-softwrap mode at the moment.)

Fri 17 Feb 2017 11:17:13 AM UTC, comment #2: Thanks reporting this other issue. I have rereported it as a separate bug, though: bug #50335. I want to reserve the current bug for double-width characters that get hidden because their right half is offscreen at the right edge. |

To reproduce, download the attached file, and run 'stty cols 49 && src/nano +2,49 --soft chinese.html'. See how the cursor seems to be on a space and how the next screen line seems to begin with a space. But toggling M-P does not show a middot in those places -- so there is something else than whitespace there. Now type an x, and see how the character 有 appears at the start of the next screen line, underneath the cursor -- so that is the character that the cursor was sitting on but that couldn't be shown because it requires two columns to be displayed. Also see how at the end of the same screen line, the character 色 has disappeared -- because it is now "split" over two screen lines and thus cannot be displayed.
