Common Unicode Characters and Compose sequences

Unicode characters I use commonly, and which have no key mapped by default.
Note Unicode code points (Unicode “codes”) can be introduced in GNOME easily with CTRL+Shift+U followed by the hex code.

Dashes ("en", "em" and "horizontal bar": –, —, ―)

  • En dash: U+2013 ⇒ –
  • Em dash: U+2014 ⇒ —
    • Also Compose + -,-,- (Compose + 3 dashes)
  • Figure dash: U+2012 ⇒ ‒ (same width as a digit in fonts with same-width digits: «1‒2‒3»)
  • Horizontal bar: U+2015 ⇒ ― (hard to distinguish from em dash in most fonts/font sizes)

U+391 = Α, U+392 = Β, U+393 = Γ, …

U+3b1 = α, U+3b2 = β, U+3b3 = γ, …

Assignment operator

U+2254 ⇒ ≔

Questioned equal to

U+225F ⇒ ≟

Unicode name QUESTIONED EQUAL TO, source: http://www.w3.org/TR/MathML2/bycodes.html

    • Also Compose, <, < and Compose, >, >
    • Also AltGr + z and AltGr + x (X-Window, layout-dependant?)
  • Typographical double: U+201c, U+201d ⇒ “ ” (HTML: ldquo and rdquo)
    • Also Compose, <, and Compose, >
    • Also AltGr + v and AltGr + b (X-Window, layout-dependant?)

  • Em space/Mutton: U+2003 ⇒ [ ] (width of 1 em), (HTML: emsp)
  • Figure space: U+2007 ⇒ [ ] (same width as a digit in fonts with same-width digits: «1 2 3», non-breaking)
