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!).
* v. 0.31:
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.
- Corrected Petite Caps and Small Caps variant for U+00F0 (eth),
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".

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:

- 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:
- Stretchable delimiters corrected in KpMath-Sans.
- Options `frenchstyle`, `partialup` and `fancyReIm` now work as intended.
* v. 0.36:
Maths fonts:
- `kpfonts-otf.sty`: Option mathcal deleted, \mathcal{} and \mathscr{}
now print different glyphs.
- mathcal substitutions corrected for `KpMath-Regular` and `KpMath-Sans`.
- Stretchable \langle, \rangle, \lAngle and \rangle delimiters are now
available in eight sizes (three bigger sizes added).
- All vertical arrows are now stretchable.
- Bug fix: stretchable right paren was broken in `KpMath-Sans`, thanks
to Tom Stotko for pointed it out!
* v. 0.37:
1. Text fonts:
- Added glyphs U+2010 and U+2011 (hyphens).
- Corrected `kpfonts-otf.sty`: option "largesmallcaps" fixed, new weights
added (\sbseries, \ltseries, \ebseries), see documentation.
- Breaking change: files `*.fontspec` changed so that the default smallcaps
are now "Petite" instead of "Small" to match the orignal kpfonts default.
2. Maths fonts:
- Completed the collection of "squares", "triangles", "diamonds" and
"lozenges".
- Tuned all "squares", "circles" and "triangles": the smaller ones are
centered on the math-axis, larger ones rest on the baseline.

no longer turned into the long variant.
- Fixed kerning after "f" in KpSans-BoldItalic.
2. Maths fonts:
- Added bold versions to \dotlessi, \dotlessj, named \mbfdotlessi,
