You may wish to investigate the mode of your console-- Unicode or whatever. Anyway, this is not a ncurses bug if you are sending raw ANSI escape codes to the console. Closing bug as invalid. I don't know if the component responsable is ncurses or another one, but the bug EXISTS and does not permit any program to work if the program itself looks for display, rectangles or lines on the console. This happens from version Redhat Linux 7.3 up to version Redhat Linux 9.0 and also in the Fedora version. The problem does not exist Redhat version 7.2 and all former versions; in all the Suse versions, Mandrake,Slackware that we tested. If someone intends to solve this problem , then we could use Fedora. Otherwise we will have to use another distribution. Your method of drawing line characters is obsolete (this is why you should use ncurses and not attempt to output raw characters) for UTF-8 based systems. To make your example work, you should do this: unicode_stop; cat text; unicode_start unicode_stop and unicode_start are script files which output the proper ANSI prefixes to do what you want. If he'd used ncurses (as part of a full-screen application rather than termcap- or terminfo- or raw-strings), ncurses does have workarounds for the missing functionality. |
