using uni2characterwidth from Unicode 11 lists.</p>
<p>Skin tone, flags, gender, and other emoji with and modifer are not<br />
joined (you will see e.g. a skin tone square + generic yellow emoji).<br />
I think joining them would cause problems in most editors, command line<br />
prompts, and other programs which use character width data, as the<br />
characters would behave as combining or emoji depending on context (like<br />
ligatures).</p>
<p>Examples:</p>
<ul class="remarkup-list">
<li class="remarkup-list-item">light thumb up: đđģ</li>
<li class="remarkup-list-item">dark thumb up: đđŋ</li>
<li class="remarkup-list-item">Polish flag: đĩđą</li>
</ul>
<p>This behavior is allowed:</p>
<ul class="remarkup-list">
<li class="remarkup-list-item"><a href="https://unicode.org/reports/tr51/#Emoji_Modifiers_Display" class="remarkup-link" target="_blank" rel="noreferrer">https://unicode.org/reports/tr51/#Emoji_Modifiers_Display</a></li>
<li class="remarkup-list-item"><a href="https://unicode.org/reports/tr51/#Emoji_ZWJ_Sequences" class="remarkup-link" target="_blank" rel="noreferrer">https://unicode.org/reports/tr51/#Emoji_ZWJ_Sequences</a></li>
</ul>
<p>It is possible to add support for sequences, but those would work<br />
only for a string width functions.</p>
<p>Some characters which can be presented as emoji are narrow (e.g. âī¸, Šī¸).<br />
Those characters are listed without "presentation" mode, which means<br />
they should be rendered as text by default (real presentation depends on<br />
renderer and/or font). Noto Sans Color Emoji renders them as wide,<br />
DejaVu Sans as narrow. Vim, bash and zsh treat them as narrow, so I made<br />
them narrow.</p>
