Special characters in password field can't be displayed #2
Description
I found this issue from day one:
First some password strings, like this one @#$^[[1;2S!EASDF and this one @#$^%^&^&&&^[[19;2~*%@, will not be able to show in bash command line(whether with echo or printf) because there were some control chacracters, ^[ in this case. I found there is a similar issue in vim edited file, which causes cat can't display the content with similar characters. Using a circumvention way like cat -v, however, can display those characters.
However, whatever I tried in bash, there's no simple way to get it across. Does anyone know?
It could be a language encoding issue as well, but where should we configure it to make it universal to different terminals at end users' sides?
