Luciole package
===============

## Description

This package provides four Unicode Math text fonts `Luciole-*.ttf` and
a companion maths font `Luciole-Math.otf`.  
They have been developed explicitly for visually impaired people
and are the result of a collaboration between the Regional Technical Center
for Visual Impairment, the type-design studio typographies.fr and
the mathematician Daniel Flipo. The Luciole project received a grant from
the Swiss Ceres Foundation and the PEP69 association, and support from
the DIPHE laboratory at the Université Lumière Lyon 2 and the association
GUTenberg.

## Installation

This package `Luciole’ is meant to be installed automatically by TeXLive,
MikTeX, etc. Otherwise,  can be installed under TEXMFHOME or TEXMFLOCAL, f.i.
text and math fonts in directory texmf-local/fonts/truetype/public/luciole/,
and luciole-math.sty, Luciole.fontspec in directory
texmf-local/tex/latex/luciole/.  
Documentation files and their sources can go to directory
texmf-local/doc/fonts/public/luciole/

Don't forget to rebuild the file database (mktexlsr or so) if you install
under TEXMFLOCAL.

Finally, make the system font database aware of the Luciole fonts
(fontconfig under Linux).

  - internal: \widearc reencoded for compatibility with my other math fonts.
  - cv00 (unavailable) replaced by cv11 to access slashed zeros.

  option "no-logos" added to prohibit their redefinition.

  - Most horizontal arrows and harpoons are now stretchable.
  - Fixed kernings between ([{ and \mij, \mity.

* v0.60
  - Improved design of large parentheses.
  - Invisible Math operators (U-2061 to U+2064) added.
  - Compatibility with Typst v0.14: all glyphs used in vertical compositions
    now sit on the baseline.
  - Documentation fixes.

* v0.70

  - Circle, diamond and lozenge operators : sizes enlarged.
  - Brackets redesigned.
  - Math table Sub/Superscripts parameters tuned, see

  - Math table fraction parameters tuned.
  - Fixed spaces' width (U+2000 to U+200B and U+205F).
  - Variation Selectors (U-FE00 and U+FE01) added; they work on all Math
    symbols listed on
    https://www.unicode.org/Public/UCD/latest/ucd/StandardizedVariants.txt

    script variants of the default calligraphic capitals (Chancery like).
