What can possibly have broken all the lowercase letters (but not caps) in my terminal?

Look at this incredible screenshot. I’m editing a commit message in Nano, within iTerm (an OS X terminal). I had just pulled changes from the master branch at [email protected]:Compass/compass.git

crazy looking terminal

Please note how all the capital letters display fine, but no lowercase letters do!

This persisted even after I closed Nano. I had to close the terminal tab.

My question is… how is that possible? What "feature" of which software does this?

Solution

  • These are VT100 line drawing characters.

    You can reproduce it with echo -e '\033(0' and exit the mode with echo -e '\033(B'.

    Alternatively, reset will reset the terminal and go back to normal.
