* Text: a word doesn't break after ?, !, } or + (URLs wrap as in PowerPoint) Unicode line breaking allows a break after ?, !, } and + inside a word, so a long URL broke after its '?' and after each '+' of a query and left the rest of the line empty. Measured in PowerPoint 2016 for Windows with latinLnBrk off (its default), none of them is a break: the word fills the line and breaks where it no longer fits, as PowerPoint already does after / and \ (break_opportunities). The same synthetic slide now wraps line for line as PowerPoint's PDF does, a Yandex search URL included. * Text tests: the first line doesn't end at the separator * Text tests: check the line is full, not that it avoids ending at a separator * Keep the Unicode break after ?, !, / outside Latin words The PowerPoint no-break rule only holds inside a word: before an ideograph (日本!語) or punctuation the Unicode break stays, as CodeRabbit pointed out. * Only letters and digits continue a word for the no-break rule AL and AI also hold symbols such as & and ×, so a!&b kept no break after !. is_word_char now also requires c.is_alphanumeric() (CodeRabbit). * Test that Latin before CJK and a separator before a space still break --------- Co-authored-by: Магда М.Г. <mail@mgmagda.ru>
