The following packages have been upgraded in the Cygwin distribution:

* unifont		15.1.01
* unifont-viewer	15.1.01
* unifont-fonts		15.1.01

GNU Unifont is a Unicode font with glyphs for all visible Unicode
Basic Multilingual Plane (the first 64K) character code points,
with supporting utilities to modify the font.

15.1.01    2023-09-12

* Glyphs updated for Unicode 15.1.0 release.
* OpenType fonts are now built by default, replacing TrueType fonts.
* New Hangul Johab 6/3/1 encoding devised by Ho-Seok Ee for building
  the Hangul Syllables block (U+AC00..U+D7A3), with new supporting
  programs johab2syllables, unigen-hangul, and unijohab2html.  This
  encoding replaces Unifont's original Hanterm-derived encoding.
  New source files hangul.h and unihangul-support.c provide support
  for rendering syllable bitmaps with all Unicode Hangul letters,
  including all ancient Hangul, through the new unigen-hangul program.
  These functions also can support user-written Hangul syllable rendering
  programs, for example on embedded systems using graphics displays.
* Added three hexadecimal digit representation CSUR/UCSUR scripts:
  - U+EBE0..U+EBEF: Boby Lapointe's "bibi-binary" notation
  - U+EBF0..U+EBFF: Bruce Alan Martin's bit location notation
  - U+ECF0..U+ECFF: Ronald O. Whitaker's triangular notation.
* Modified hexdraw to support bitmap manipulation of up to 64 rows
  by 128 columns for 64-by-128 graphics display screen drawing support.
  Added the unihexpose program to transpose Unifont glyphs, for use
  with graphics display controller chips that encode each byte as
  8 rows by 1 column, left to right.

NOTE 

This release does not include Truetype format, only Opentype format
Unifont fonts, as previously announced.
One known issue with TrueType is Pango combining character rendering,
which will not be fixed; the Pango maintainers pretty much just want
to support OpenType.
As these fonts are bitmap glyphs rendered into modern font formats,
both formats should render the same glyphs.
All modern systems support both Opentype and Truetype format fonts,
so there should be few or no issues if future releases provide only
Opentype format Unifont, which are also less than half the file size
of the Truetype format.
If anyone encounters issues using the Opentype format Unifont,
please let us know so we can address any issues.
