> write(1, "+-\33[7b+\33[25G", 12) = 12 This tells your terminal to draw a "+", followed by a "-" which should then be repeated seven more times (\33[7b), followed by a "+". So, nano (by way of ncurses) gives your terminal a correct sequence of codes to draw the stuff that should be drawn. But apparently your terminal (Putty) does not understand the \33[nb code and ignores it, resulting in a garbled display.
Please see https://stackoverflow.com/questions/46507473/ncurses-in- urxvt-does-not-print-repeating-characters. And https://invisible- island.net/ncurses/ncurses.faq.html#xterm_generic (the paragraphs after the table). The problem is in Putty: it says it is an xterm (or xterm-compatible), but it isn't. Solution: set your TERM to what it should be: putty. Look in /usr/share/terminfo/p/ for other possibilities. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to nano in Ubuntu. https://bugs.launchpad.net/bugs/1858293 Title: Missing repeated characters Status in nano package in Ubuntu: New Bug description: Nano 2.9.3 Ubuntu 18.04.3 LTS - Linux 4.14.157-171 armv7l ARMv7 Processor rev 3 (v7l) Ubuntu 18.04.3 LTS - Linux 4.9.196-63 aarch64 Amlogic S922X rev a (4 A73 + 2 A53) This issue is repeatable on more than 6 each different machines of the above configurations. I am using ssh via Putty to log in via terminal screen. I am using nano defaults. I have not changed anything nor do I open with any arguments. I use nano <filename> and it's not associated with any extension. It behaves the same for all files, even no extension files. Nano is not changing the file, it's just not displaying correctly. The characters are there and they save properly, they're just not visible on the terminal screen. Using WinSCP presents no issues as I am using my local Windows text editor. If I use vi to view the file there are no problems. If I use cat to view the file there are no problems. If I use tail to view the file there are no problems I do not experience this issue on: Nano 2.5.3 Ubuntu 16.04.6 LTS - Linux 4.14.5-92 armv7l ARMv7 Processor rev 3 (v7l) If I take any file that has repeat characters such as: ############ ----------------- ||||||| Nano 2.9.3 will not display all of the continuous repeat characters in the row. For example: Copy and paste ############ is displayed as: # <-- But end of line is correct If I copy that line from the file in nano editor and paste it into another non nano editor I get: # as the paste result This is the same for all different repeated characters. If I keyboard type ############################## nano will display it until nano is closed and then the same file is reopened. Then it's same as above, one # but end of line is correct.
