CSS only has the fixed tab-size grid, so a tab that resolves to one of the
paragraph's stops is measured and given the exact advance as an inline margin.
A hanging indent implies a stop at the text position, as in Word.
Lists were padded 1.5rem per level on screen while the DOCX and ODT
exports place item text at LIST_LEFT_STEP_CM (1.27cm) per level, so the
editor disagreed with its own output and with Word and LibreOffice by
6.4mm on the first level, doubling with each nesting level.
Only the block's left margin was read, so w:firstLine, w:hanging and
fo:text-indent were dropped: every hanging-indent paragraph rendered with
its first line flush with the rest instead of outdented.
Stored as the signed indentFirst attr in cm (negative = hanging) and
rendered as CSS text-indent. Word splits it into two exclusive
attributes by sign, ODF keeps one signed value.
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.
