w:evenAndOddHeaders, w:titlePg and w:pageBreakBefore were treated as on
whenever the element existed, but w:val="false"/"0"/"off" turns them off
and both Word and the docx lib write that explicit form.
A file with <w:evenAndOddHeaders w:val="false"/> therefore took the
even-page header variant on every second page, which is empty — the
header and footer vanished from page 2 onwards.
Widow-orphan control was hardcoded on. It is a per-paragraph property in
both formats, so a file that turns it off paginated differently from
Word and LibreOffice.
Stored as the widowControl attr next to breakBefore. DOCX resolves
w:widowControl direct-then-style-chain-then-docDefaults; ODF reads
fo:widows/fo:orphans, where only an explicit 0 means off (absent is the
XSL-FO default of 2). Export rides the existing PBX sentinel rather than
adding a pass.
Cells padded 0.1cm on all sides; Word and LibreOffice use 0.19cm left and
right and none top or bottom. Text sat 0.7mm too far left and every row
was 2mm too tall, so the offset accumulated down a table.
odf-kit only writes the fo:padding shorthand, which ODF defines as a
single length — LibreOffice drops a two-value form — so the export
expands it per side.
Single spacing is the font's natural line height. The hardcoded 1.15 is
Liberation Serif's (and Liberation Sans' and Caladea's), but Carlito
needs 1.2208 and Liberation Mono 1.1333 — measured against LibreOffice
at 12pt. A Calibri body ran 6% too tight, drifting a line per page.
Emitted next to font-family, so an explicit line spacing still wins.
Body paragraphs carry no w:pStyle, so the default style never reached
usedStyles and Standard kept the editor's Liberation Serif 12pt. Run
suppression meanwhile resolves against w:docDefaults, so the file's body
font was dropped with no run mark left to render it: a Calibri 11pt Word
document rendered as Liberation Serif 12pt.
