t(source, values) returns a node once a value is an element, so a link or a styled figure stays inside the one sentence a translator reorders. In a right-to-left locale every argument is isolated (U+2068..U+2069 in a string, <bdi> around an element): 1,150–1,400 no longer reads 1,400–1,150 in Arabic. English output is unchanged byte for byte. phrase(source) marks English written as data, for t(item.label) where it is drawn. i18n-extract --catalogs reads t and phrase literals from the syntax tree into en-US.json; --prune drops what no reader asks for. i18n-translate --jobs n asks several locales at once. @hanzo/i18n 0.4.0.
