Wez Furlong c68b55ba4f termwiz: clamp grapheme column width to 2 
This isn't ideal, but it addresses a couple of issues:

* wezterm currently has a debug assertion that this is true
* Korean text in NFD is currently recognized as having a width of 3
  when it should be 2 due to upstream issue
  https://github.com/ridiculousfish/widecharwidth/issues/16
* NFD and NFC should render the same for the sample text in
  https://github.com/wez/wezterm/issues/1474 but don't as a result

Clamping to 2 "solves" these, at the cost of potentially other
weird stuff in the future.  It seems like a reasonable tweak
for the time being!

Terminal Wizardry

This is a rust crate that provides a number of support functions for applications interested in either displaying data to a terminal or in building a terminal emulator.

It is currently in active development and subject to fairly wild sweeping changes.

Included functionality:

  • Surface models a terminal display and its component Cells
  • Terminal attributes are aware of modern features such as True Color, Hyperlinks and will also support sixel and iterm style terminal graphics display.
  • Surfaces include a log of Changes and an API for consuming and applying deltas. This is a powerful building block for synchronizing screen instances.
  • Escape sequence parser decodes inscrutable escape sequences and gives them semantic meaning, making the code that uses them clearer. The decoded escapes can be re-encoded, allowing applications to start with the semantic meaning and emit the appropriate escape sequence without embedding obscure binary bytes.
  • Capabilities allows probing for terminal capabilities that may not be included in the system terminfo database, and overriding them in an embedding application.
  • Terminal trait provides an abstraction over unix style ttys and Windows style console APIs. Changes from Surface can be rendered to Terminals. Terminals allow decoding mouse and keyboard inputs in both blocking or non-blocking mode.
  • Widget trait allows composition of UI elements at a higher level.
  • LineEditor implements shell-like line editing functionality.

Windows Support

Termwiz understands how to work with both the legacy console APIs and the new PTY and virtual terminal features available in Windows 10, allowing for true color terminal applications on Windows 10.
