-notes = "In Edit text, one click on text in a supported grouped Form prepares its page (one undoable step) and opens the paragraph clicked, so its existing source glyphs are edited directly; nothing is prepared while pages are only shown, a drag still moves the selected group, and a click on grouped artwork that preparation wouldn't open (a logo, a refused group) selects it as before. text_prepare does the same headlessly, with the same code as Ungroup. Unsafe groups remain intact and are reported by text_prepare and in the repair log when the page is prepared, as is text grouped more than eight levels deep; image-only forms are left grouped. Narrow legacy THSarabunPSK character-map recovery, checked glyph by glyph against the subset's own advances, is recorded, also for text that was never grouped (text_prepare). Legacy Thai source editing reuses original font programs, positional glyphs and same-face subsets (a Thai run split across subsets is shaped cluster by cluster; what no subset can show in its codes is shaped whole by a complete program of the face, such as one from Load font), preserving Regular/Bold, point size, spacing and paint. A different Thai family requires explicit selection; the Noto replacement is Regular only; mixed contextual style runs remain limited. The Edit tab turns Edit text & images on at once, as in Acrobat (leaving the tab puts the tool down and applies an edit in progress); Esc in an open paragraph leaves its text and selects its box, so Delete removes it (the unapplied draft is discarded); click a paragraph box and retype it in place (font reused or Helvetica substituted, colour and spacing kept, rewrapped); a page's /Contents pieces are parsed joined, so a line whose operands and operator sit in different pieces is listed and edited (lines and paragraphs still don't join across pieces; Edit image still parses each piece alone); drag a box to move it or its right-edge handle to rewrap it (edit.text-move-resize); per-character formatting changes are next Since #1116: mixed-style visual regions retain source rows, subset encodings, colour and baseline anchors in one textless-background editor. Explicit paragraph/heading scopes constrain grouping; compatible graphics planes permit cross-stream regions. Full matching document fonts complete absent subset glyphs; installed/file selection, TrueType/OpenType-CFF embedding and disjoint UTF-8 range styles have save/reopen coverage. Single-face OpenType shaping/bidi retains logical text through ToUnicode/ActualText. Replacement text the paragraph's font can't show takes the craft-fonts Japanese faces when they draw all of it (Uzbek қ, Kazakh ә are in none of them), else the bundled Inter face, so those letters write in every build (#2593). Legacy non-SFNT preview, mixed-font/style contextual runs, full structure-tree preservation and author intent in untagged PDFs remain limited; Styled-path outline fallback batches by actual face with 240 glyphs per font and preserves source styles; adjacent equal-font/style characters form runs. At most 15360 distinct fallback glyphs per styled paragraph; missing glyphs are refused before fallback objects are written. Glyph coverage, mixed contextual shaping, single-style fallback and stale-font cleanup are unchanged; see docs/editing-existing-text.md. Text drawn inside a Form XObject (HTML-to-PDF output, stamped or imposed pages) is grouped artwork until Ungroup (artwork right-click menu; image_edit action ungroup) draws that placement in place with its resources merged; knockout groups and transparency groups that blend inside, are drawn translucent or blend in a colour space other than the page's are refused, as are forms with resources of their own whose /DefaultGray, /DefaultRGB or /DefaultCMYK differs from the page's, either side lacking it included (ISO 32000-2 §8.6.5.6), and forms drawn inside a text object or an unfinished path, each resource name is read from the operand the renderer uses (a surplus operand before it is ignored; an operator whose operands can't be read is refused), and a pattern the form fills with is drawn from a copy whose /Matrix carries the placement (ISO 32000-2 §8.7.2), so ungrouping never changes the pixels."
