nv-charter

This version omits a few ligatures that consistently looked bad on e-ink displays and has adjusted metrics for improved line height. A more clarified license which is also included as part of the distributed font files.

How was this made?

A few ligatures were removed, namely: ff, ffi, ffl, fl, fi.
A tweak was made to ensure the fi kern pair looks good now that the ligature is gone.
Improved line height metrics were set (updated ascent/descent metrics).
The font was renamed and re-exported with FontForge.
The copyright notice has been updated to reflect the new name.

I've included the FontForge files in this repository.

XCharter is an extension of Bitstream Charter, whose original license is reproduced below, as required under the terms of that license. The extension provides small caps, oldstyle figures and superior figures in all four styles, accompanied by LaTeX font support files.

NV Charter is based on XCharter, but contains some manual tweaks and adjustments to metrics for an improved digital reading experience.
