The test uses U+07FF NKO TAMAN SIGN because it is the highest
code point having a two-byte UTF-8 representation.
This character is a new single-width punctuation character in
Unicode 11, such that mandoc now does correct horizontal spacing.
We already used the code point for the test before it was assigned,
which resulted in weird spacing because wcwidth(3) returns -1 for
unassigned code points.

by the <p> HTML element and use the html_fillmode() mechanism
for .Bd -unfilled, just like it was done for man(7) earlier, finally
getting rid both of the horrible <div class="Pp"></div> hack and
of the worst HTML syntax violations caused by nested displays.
Care is needed because in some situations, paragraphs have to remain
open across several subsequent macros, whereas in other situations,
they must get closed together with a block containing them.
Some implementation details include:
* Always close paragraphs before emitting HTML flow content.
* Let html_close_paragraph() also close <pre> for extra safety.
* Drop the old, now unused function print_paragraph().
* Minor adjustments in the top-level man(7) node formatter for symmetry.
* Bugfix: .Ss heads suspend no-fill mode, even though .Ss doesn't end it.
* Bugfix: give up on .Op semantic markup for now, see the comment.

* Add two missing characters, \('Y and \('y.
* The Weierstrass p is not capital, see http://unicode.org/notes/tn27/.
* Add a groff-compatible ASCII transliteration for U+02DC: "~".

at all.

causes horrible churn anyway, profit of the opportunity to stop
excessive testing, such that this is hopefully the last instance
of such churn. Consistently use OpenBSD RCS tags, blank .Os,
blank fourth .TH argument, and Mdocdate like everywhere else.
Use -Ios=OpenBSD for platform-independent predictable output.

with "literal", by the way, it means "no fill"):
* Use <pre> such that whitespace is preserved.
* Preserve lines breaks.
* For font alternating macros, avoid node recursion which required
scary juggling with the fill state. Instead, simply print the text
children directly.
Missing feature first noticed by kristaps@ in 2011,
the again reported by afresh1@ in 2016,
and finally reported here: https://github.com/Debian/debiman/issues/21 ,
which i only found because of Shane Kerr's comment here:

HTML code even more humanly readable.
While here,
- collapse multiple consecutive space characters in filled text
- and insert a blank between style entries.

No change of HTML semantics intended.

Sometimes, even i'm surprised how much stuff these tests keep track of.
Originally, they were only intended to catch regressions in mandoc...

fixed wcwidth(3) for various unusual characters.
|

|

These surrogates are not valid Unicode codepoints,
so treat them just like any other undefined character escapes:
Warn about them and do not produce output.

changed the output of wcwidth(3) for some weird Unicode characters,
causing harmless whitespace changes in mandoc(1) output; fix up the
regression suite accordingly.
The processing of the characters themselves still works correctly,
as it did before, and that's what these tests are intended to make
sure. They were never intended to check for whitespace issues.
Problem reported by jsg@.

It accepted invalid byte sequences like 0xc080-c1bf, 0xe08080-e09fbf,
0xeda080-edbfbf, and 0xf0808080-f08fbfbf, produced valid roff Unicode
escape sequences from them, and the algorithm contained strong
defenses against any attempt to fix it.
This cures an assertion failure in the terminal formatter caused
by sneaking in ASCII 0x08 (backspace) by "encoding" it as an (invalid)
multibyte UTF-8 sequence, found by jsg@ with afl.
As a bonus, the new algorithm also reduces the code in the function
by about 20%.

Require exactly 4, 5 or 6 hex digits and allow nothing else.
This avoids mishandling stuff like \[ua] and \C'uA' as Unicode
and also fixes underlining in eqn(7) -Thtml output which uses \[ul].

It is already documented in the Heirloom troff manual,
and groff handles it as well.
Bug reported by Bjarni Ingi Gislason <bjarniig at rhi dot hi dot is>
on <bug-groff at gnu dot org>. Well, admittedly, that bug was reported
against groff, but mandoc was even more broken than groff with respect
to this syntax...
