Indirectly related story from my workplace: the application that I maintain changes some terminal line settings, such that after it is run, we have to use Ctrl-H instead of backspace (unless we also change PuTTY settings to send Ctrl-H for backspace). This means that sometimes people accidentally create files whose name is a backspace. These cannot be seen directly as '\127' via ls (or at least the default Solaris ls; not sure what GNU does), but instead as the output missing a character, usually padding, so people do not realise it is a problem. Then it causes issues when the file gets caught in globs that process all files in the directory, but the offending file is almost invisible, leaving the user confused. And we cannot change the program not to change terminal settings because who knows what that will break!
