`ApplyGujaratiReorder`

Signature

function ApplyGujaratiReorder(const Wide: UnicodeString): UnicodeString;

Purpose

Applies the Gujarati reorder pre-pass to Wide and returns a UnicodeString prepared for cmap and GSUB consumption. Text outside Gujarati remains byte-stable, so callers can route mixed text without changing unrelated runs

Coverage

Gujarati uses the gujr script record for U+0A80-U+0AFF. The documented path covers R1-R5 with no split matras while preserving API behaviour for producer-side shaping
ApplyIndicReorder dispatches to this helper when the active codepoint range matches U+0A80-U+0AFF

Example

var
  Wide: UnicodeString;
begin
  // Input: KA + AA(post) + U(below) + E(above) + I(pre)
  Wide:= Doc.ApplyGujaratiReorder(#$0A95#$0ABE#$0AC1#$0AC7#$0ABF);
  // Wide is now: I + KA + E + U + AA  (canonical 5-buffer order)
end;
