iTerm doesn't support ANSI overline attribute

Thanks for filing an issue! Please answer the questions below so I can help you.

  • iTerm2 version: 3.1.7
  • OS version: 10.13.6
  • Attach ~/Library/Preferences/com.googlecode.iterm2.plist here (drag-drop from finder into this window)
  • Attach a debug log, if possible. Instructions at https://iterm2.com/debuglog
  • Are you reporting a performance issue or a hang? Please attach a sample. Instructions at https://gitlab.com/gnachman/iterm2/wikis/HowToSample
  • Are you reporting a crash? No
  • Are you reporting excessive memory usage? No

Detailed steps to reproduce the problem:

  1. Output an ESC[53m sequence, then a couple characters, then ESC55m to put things back to normal, then some more chars
  2. Observe the first characters output lack a line over them (try this with Gnome Terminal or other vte-based terminal)
  3. Profit (and check https://en.wikipedia.org/wiki/ANSI_escape_code)

What happened: Nothing, really

What should have happened: Characters with a bar on top of them
