>The kpfonts-otf package
========================

## Description

`kpfonts-otf` is meant as a replacement, for LuaLaTeX and XeLaTeX users,
of Christophe Caignaert’s `kpfonts` package. Christophe’s Type1 fonts have
been converted to OpenType using fontforge and Adobe's AFDKO bundle.
The package is still experimental, bug reports and suggestions are welcome.

## Contents

* the `font/` directory holds 21 OpenType fonts (16 for text and 5 for maths);
* the `tex/`  directory holds the style file kpfonts-otf.sty and
  fontspec configuration files;
* the `doc/`  directory holds documentation in English and French and
  a table of available maths symbols comparing kpfonts-otf to LatinModern,
  STIXTwo, Erewhon, TeXGyreTermes, Garamond and Libertinus.

## Installation

This package is meant to be installed automatically by TeXLive, MikTeX, etc.
Otherwise, `kpfonts-otf` can be installed under TEXMFHOME or TEXMFLOCAL, f.i.

+ alls fonts (`fonts/*.otf` files) in directory
  `texmf-local/fonts/opentype/public/kpfonts-otf/`
+ style and fontspec files (`tex/kpfonts-otf.sty` and `tex/*.fontspec`) in
  directory `texmf-local/tex/latex/kpfonts-otf/`
+ documentation (from doc/ directory) in
  `texmf-local/doc/fonts/public/kpfonts-otf/`

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

Finally, you may want to make the system font database aware of the
`kpfonts-otf` fonts (fontconfig under Linux).

## Changes
* First release version: 0.30 (experimental, expect changes!).

  Fixed inconsistent widths/sidebearings for six glyphs:
  =  ≠  <  ≤  >  ≥ (all five maths fonts affected, original Type1 too).

* v. 0.32:
  1. Text fonts:
     - `kpfonts-otf.sty` corrected: the "light" option didn't work properly.
     - kpfonts-otf should now cover all glyphs in TS1 encoding (`textcomp.sty`).
     - The height of all diacritics has been reviewed and corrected.
     - New combining diacritics added : U+0310, U+0323, U+0325, U+0327, U+0328.
     - New glyphs added: U+0110 (Dcroat), U+0111 (dcroat), U+0123 (gcircumflex),
       U+0126 (Hbar),  U+0127 (hbar), U+0129 (itilde), U+012B (imacron),
       U+012D (ibreve), U+0135 (jcircumflex), U+0166 (Tbar),  U+0167 (tbar)
       and their counterparts in Petite Caps and Small Caps.

       U+00FE (thorn), U+0111 (dcroat)  and U+014B (eng).
     - Optional ft and tt ligatures added, see feature "Ligatures=Required".
     - Variants for ligatures fi ffi fl ffl added, see "Alternate=1".
     - (faked) slanted fonts added to match kpfonts T1 version.
  2. Maths fonts:
     - Corrected mismatch between mitl (U+1d459) and ell (U+2113).
     - Slanted versions for \shortparallel and \nshortparallel
       and for \gtreqless, \lesseqgtr, \gtreqqless, \lesseqqgtr added.
     - Stretchy accents \wideoverbar, \widebreve, \widecheck added.
     - Reduced boldness for superscripts and supersuperscripts.
     - New option "tight" to reduce horizontal spaces in maths mode
       (same settings as \pkg{fourier} and \pkg{fourier-otf}).

* v. 0.33:
    - Roman Text fonts:
      Added 54 glyphs in Latin-ExtendedA range (mostly complete now).
    - Maths fonts:
      Fixed inconsistencies in superscripts and supersuperscripts metrics.

* v. 0.34:
  Massive glyph cleaning: many spurious control points deleted in glyphs
  for both Maths and Text fonts.

  1. Text fonts:
     - kernings before and after quoteright improved.
     - German capital Eszet (U+1E9E) added, in Petite and Small caps too,
       feature "StylisticSet=2" added to get SS instead of capital Eszet.
     - diacritics corrected in `KpRoman-LightItalic` (some were upright).
     - breaking change: feature "Alternate=1" changed to "StylisticSet=1"
       as it didn't work with XeTeX.
  2. Maths fonts:
     -  metrics (width, italic correction) reviewed.
     -  accents ovhook (U+0309), candra (U+0310), vertoverlay (U+202D) added.

* v. 0.35:
  1. Text fonts:
     - Added 54 glyphs in Latin-ExtendedA range for `KpSans` fonts.
     - Euro symbol added in Roman, Sans and Mono, option StyleSet=3 to
	   trigger it.
     - Added missing anchors for "dot below" on P, p, p.pc, p.sc, a.sc.
     - HarfBuzz renderer no longer loaded for HBLuaTeX engine, new option
       "harfbuzz" to force loading it (`kpfonts-otf.sty`).
  2. Maths fonts:
     - Extensible delimiters corrected in KpMath-Sans.
     - Options `frenchstyle`, `partialup` and `fancyReIm` now work as intended.

      now print different glyphs.
    - mathcal substitutions corrected for `KpMath-Regular` and `KpMath-Sans`.
    - Extensible \langle, \rangle, \lAngle and \rangle delimiters are now
      available in eight sizes (three bigger sizes added).

       are now "Petite" instead of "Small" to match the orignal kpfonts default.
  2. Maths fonts:
     - Completed the collection of "squares", "triangles", "diamonds" and
       "lozenges".

     - \perp, \bot, \rightangle, \angle, \measuredangle, \sphericalangle
       shifted up, their bottom rests on the baseline now.
