A run of Unicode code points now needs one pair of carets, not one pair
each: ^9053 53EF 9053^ renders the characters adjacently, and a single
character inside such a run stands for itself. An invalid code point is
an error naming the position that wrote it, rather than an apology
rendered into the finished document; noncharacters are refused alongside
surrogates; and a code point that lands on a Klammertext special is safe
through the re-reads that assemble a document. The character tables now
produce the precomposed form, so a diacritic written as ^a" and one typed
directly are the same text to a search or a copy-paste.
"kdesc -u" describes how to write a Unicode character, with tables of
glyphs beside the codes that produce them. It is new and not yet
complete: it predates the sequence form and the typeface klammer below.
A typeface and a style are no longer both called "font". A typeface is a
family resolved by name; a style code is the one letter naming a type
style. So @document takes :serif_typeface and its siblings, a table takes
:style, captions take :caption_style and :caption_size, the uniform scale
is :text_scale, and the command is "kdesc --typeface". This renames
arguments a document may already use; an old name is a located error
rather than a silent omission.
@typeface sets a passage in another typeface for the length of that
passage:
@typeface Noto Sans Egyptian Hieroglyphs | ^132AA 133CF^ :scale 1.5 @
Writing the klammer is the whole declaration -- the document resolves the
typeface, embeds it in what it produces, and carries its license along.
Two typefaces for scripts no text font covers now ship with Klammertext:
Noto Sans Egyptian Hieroglyphs and Noto Sans Cuneiform. Every typeface in
the distribution now carries its license file.

This snapshot carries sks/tns/, the translation directory, into the
distribution for the first time, together with the two default font
families its stylesheet names.
sks/tns/ holds two converters in opposite directions. md_to_sks.py
converts Markdown to Klammertext, recording what it cannot convert exactly
as "#[MD ... ]#" markers so a draft carries its own worklist. md_to_pdf.py
renders Markdown straight to PDF through a headless Chromium driven over the
DevTools Protocol, bypassing Klammertext entirely -- the route for a
document that is not ready to convert, and a permanent one for Markdown that
Klammertext cannot represent well. Neither is loaded by the SKS; md_to_pdf
needs markdown-it-py, which it keeps in a virtual environment of its own and
creates with --setup.
The everyday form of the second is the mdpdf command, a shell function in
sks/tns/mdpdf.sh that env/runtime.env sources, so anyone with the
Klammertext environment has it:
mdpdf notes.md # writes notes.pdf beside it
It supplies the house fonts, the size matching, and the code wrapping,
completes on *.md at the TAB key, and takes its defaults from MDPDF_*
variables so one can be changed in a shell profile without copying the
function. It is POSIX shell rather than zsh, since runtime.env is sourced
from bash profiles too.
Two things the stylesheet does that a print stylesheet usually cannot. Code
lines are wrapped to a column count MEASURED from the rendered page rather
than written down -- the browser is asked how many characters a code box
holds, over every box in the document, so the wrapping stays right when the
fonts, sizes or margins change. And the page number is a CSS Paged Media
margin box, which current Chromium implements, so it is set in the
document's own face instead of the browser's generic sans.
fnt/ gains EB Garamond and Source Sans 3, the serif and sans the stylesheet
asks for by default.
