为 Ǝ 和 ə 编写按键序列?

为 Ǝ 和 ə 编写按键序列?

/usr/share/X11/locale/en_US.UTF-8/Compose(Ubuntu 18.04) 定义了“e”字符的重音变体的组合序列:

<dead_acute> <U018E>                    : "Ǝ́"   # LATIN CAPITAL LETTER TURNED E WITH ACUTE
<dead_grave> <U018E>                    : "Ǝ̀"   # LATIN CAPITAL LETTER TURNED E WITH GRAVE
<dead_circumflex> <U018E>               : "Ǝ̂"   # LATIN CAPITAL LETTER TURNED E WITH CIRCUMFLEX
<dead_caron> <U018E>                    : "Ǝ̌"   # LATIN CAPITAL LETTER TURNED E WITH CARON
<dead_macron> <U018E>                   : "Ǝ̄"   # LATIN CAPITAL LETTER TURNED E WITH MACRON
<dead_tilde> <U018E>                    : "Ǝ̃"   # LATIN CAPITAL LETTER TURNED E WITH TILDE
<dead_acute> <dead_tilde> <U018E>       : "Ǝ̃́"   # LATIN CAPITAL LETTER TURNED E WITH TILDE AND ACUTE
<dead_grave> <dead_tilde> <U018E>       : "Ǝ̃̀"   # LATIN CAPITAL LETTER TURNED E WITH TILDE AND GRAVE

<dead_acute> <U01DD>                    : "ǝ́"   # LATIN SMALL LETTER TURNED E WITH ACUTE
<dead_grave> <U01DD>                    : "ǝ̀"   # LATIN SMALL LETTER TURNED E WITH GRAVE
<dead_circumflex> <U01DD>               : "ǝ̂"   # LATIN SMALL LETTER TURNED E WITH CIRCUMFLEX
<dead_caron> <U01DD>                    : "ǝ̌"   # LATIN SMALL LETTER TURNED E WITH CARON
<dead_macron> <U01DD>                   : "ǝ̄"   # LATIN SMALL LETTER TURNED E WITH MACRON
<dead_tilde> <U01DD>                    : "ǝ̃"   # LATIN SMALL LETTER TURNED E WITH TILDE
<dead_acute> <dead_tilde> <U01DD>       : "ǝ̃́"   # LATIN SMALL LETTER TURNED E WITH TILDE AND ACUTE
<dead_grave> <dead_tilde> <U01DD>       : "ǝ̃̀"   # LATIN SMALL LETTER TURNED E WITH TILDE AND GRAVE

但奇怪的是,它没有为角色本身定义序列。

它甚至没有定义相似的字符(U+2203 ∃“存在”)和(U+0259 ə“schwa”)。

这些字符是否有某种序列(Ǝ U+018E 和 ϝ U+01DD),还是我必须在 ~/.XCompose 文件中自己定义它?

如果不,为什么它们不是与重音版本一起定义的吗?

在 Ubuntu 中,字符本身的序列是Compose+ e+ e
