ODF carries western, asian and complex-script font properties side by side and a word processor picks by the character's script; the importer read only the western pair, so a complex-script run came out at the document default. Decided per run — the finest split the model has — so a document with no complex script is untouched, and our own export (all three written alike) round-trips. Measured: a two-column page's line pitch 7.5mm -> 5.9 against LibreOffice's 6.0.
