fonts/shaping: respect the Presentation selection for a cluster This commit annotates fonts with a boolean that indicates whether we think it contains glyphs with emoji presentation, and then passes the cluster.presentation field down to the shaper. If the presentation doesn't match the current font in the fallback, then it will be skipped until we exhaust its options. `wezterm ls-fonts` also shows whether we think a font has emoji presentation. refs: #997 2021-08-11 19:11:59 +03:00

Respect emoji-variation-sequences.txt Not all codepoints are valid when combined with a presentation selector. This commit ensures that we respect the valid sequences defined by the current version of unicode (version 14). refs: #1231 refs: #997 2021-11-26 00:34:32 +03:00			`echo -e "\u270a\ufe0e Raised fist, explicit text presentation (invalid; no effect)"`

introduce unicode_version config This is a fairly far-reaching commit. The idea is: * Introduce a unicode_version config that specifies the default level of unicode conformance for each newly created Terminal (each Pane) * The unicode_version is passed down to the `grapheme_column_width` function which interprets the width based on the version * `Cell` records the width so that later calculations don't need to know the unicode version In a subsequent diff, I will introduce an escape sequence that allows setting/pushing/popping the unicode version so that it can be overridden via eg: a shell alias prior to launching an application that uses a different version of unicode from the default. This approach allows output from multiple applications with differing understanding of unicode to coexist on the same screen a little more sanely. Note that the default `unicode_version` is set to 9, which means that emoji presentation selectors are now by-default ignored. This was selected to better match the level of support in widely deployed applications. I expect to raise that default version in the future. Also worth noting: there are a number of callers of `unicode_column_width` in things like overlays and lua helper functions that pass `None` for the unicode version: these will assume the latest known-to-wezterm/termwiz version of unicode to be desired. If those overlays do things with emoji presentation selectors, then there may be some alignment artifacts. That can be tackled in a follow up commit. refs: #1231 refs: #997 2021-11-25 18:53:07 +03:00
