Add text wrote Arabic as "?" (standard-14 fonts, WinAnsi). Items with Arabic are now shaped with the craft-fonts Arab face through harfrust (already in the tree via egui) and laid out line by line in display order with unicode-bidi (UAX #9), so Arabic mixed with Latin, digits and brackets reads correctly. Each cluster (a letter with its dots or marks) is one glyph of a Type 3 font drawn from the face's outlines, with a ToUnicode entry, so text extraction, copy and search get every letter once and no font file is embedded. - fonts: shape_arabic / arabic_glyph / arabic_has / document_arabic_font; japanese_glyph's bounded outline code is shared as bounded_outline. - edit: draw_arabic and type3_arabic; wrapping measures shaped words. Fonts get names free on the page (a full save renumbers objects, not resource names) and are removed when the item is updated or deleted. Outlines are read before anything is written. - Without the face, adding Arabic is a clear error that changes nothing; an existing item holding Arabic still moves, drawn as "?" as before. - Non-Arabic items are drawn exactly as before.
