CHANGELOG

2024-04-04

Added transpose and hermitian transpose: A𞁀 and Aᵸ.

Key combinations: \transpose/\hermitian or provisional \tp/\htp

We abuse the two Cyrillic characters:

  • 𞁀: U+1E040 Modifier Letter Cyrillic Small Te
  • ᵸ: U+0480 U+1D78 Modifier Letter Cyrillic En

In unicode-symbols.sty we define these as \superscript{\mkern-1.5mu\mathsf{T}\mkern-1.5mu}} and \superscript{\mkern-1.5mu\mathsf{H}\mkern-1.5mu}} respectively. We remove half a thinspace (\!=-3.0mu) on each side of the letter to improve spacing.

2024-04-02

  • Added missing letter-like symbols (now complete)

2024-03-08

  • Revamped the installation script, now with argparse.
  • Refactored the installation procedure. Now expects folders with .tsv files as input.
  • Split custom icons into separate files, according to Unicode block.

2024-02-27

  • Added italic and bold italic Greek variants to unicode-symbols.sty.
  • Added missing "variant" Greek symbols such as 𝛡 (\bfvarpi)

2024-02-26

Main work was refactoring the unicode-symbols package. It is now located in the latex-package directory. Additionally, a main achievement is the novel code for sub- and superscripts which automatically combines multiple sub- and superscripts into a single command.

For example, $xᵢⱼ$ will render identically to $x_{ij}$ ($x_{ij}$).

2024-01-23

Finally, merged a dev branch into main.

⚠️ Added unicode-symbols.sty which provides a subset of the Unicode symbols for usage with pdflatex. ⚠️

  • Revamped the generation script
  • renamed .csv files to .tsv, since we use tabs as separators
  • added custom_icons.tsv with additional Unicode icons
  • added custom_symbols.tsv with additional Unicode symbols
    • DIGIT variants
      • circled numbers ①, ②, ③, … (\o1, \o2, … \o20)
      • bold digits 𝟎, 𝟏, 𝟐, … (\bf0, \bf1, … \bf9)
      • double-struck digits 𝟘, 𝟙, 𝟚, … (\bb0, \bb1, … \bb9)
      • sans-serif digits 𝟢, 𝟣, 𝟤, … (\sans0, \sans01, … \sans9)
      • bold sans-serif digits 𝟬, 𝟭, 𝟮, … (\bsans0, \bsans1, … \bsans9)
      • typewriter (monospaced) digits 𝟶, 𝟷, 𝟸, … (\tt0, \tt1, … \tt9)
      • digits with stop ⒈, ⒉, ⒊, … (\1., \2., … \20.)
      • parenthesized digits ⑴, ⑵, ⑶… (\(1), \(2), … \(20))
    • LETTER variants
      • small capital letters ᴀ, ʙ, ᴄ, … (\scA, \scB, … \scZ)
      • circled uppercase letters Ⓐ, Ⓑ, Ⓒ, … (\oA, \oB, … \oZ)
      • circled lowercase letters ⓐ, ⓑ, ⓒ, … (\oa, \ob, … \oz)
      • parenthesized Latin letters ⒜, ⒝, ⒞, … (\a, \b, … \z)
    • Roman numerals
      • uppercase Roman numerals Ⅰ, Ⅱ, Ⅲ, … (\RM1, \RM2, … \RM1000)
      • lowercase Roman numerals ⅰ, ⅱ, ⅲ, … (\rm1, \rm2, … \rm1000)
    • Additional Aliases from existing Unicode characters
      • ✅ (\CMARK), ❌ (\XMARK)
      • ‖ (\|)
      • ﹢ (\+), ﹣ (\-), (unary plus/minus)
      • Small Form Variants
      • Full width variants: ， (\,, replace $,\,$), ： (\:, replaces $\colon$), ； (\;, replaces $;\,$)
      • etc.
  • Added extraction code for complete Unicode database for future work.

Ideas for future work:

  • Support an AutoKey alternative that works with Wayland.
  • It would be really nice to have something similar to language server protocol for these Unicode expansion, facilitating auto-completion and discovery.
  • Auto-generate the unicode-symbols.sty file from the Unicode database.
  • Allow installing subset of Unicode symbols, e.g. only math symbols, or only arrows, etc.
    • In particular "basic plane" symbols, since overleaf.com only supports those.
