+ * new text using raw font charcodes (skipping PDFium's broken reverse Unicode→CID lookup for
+ * embedded subset fonts). What PDFium does NOT expose is the byte-encoding side of an existing font
+ * - given a PDFont and a Unicode string, what are the bytes the font's encoding produces? PDFBox
+ * does have that ({@link PDFont#encode}).
+ *
+ * <p>This endpoint accepts the source PDF + a "locator" describing where to find the font in
+ * question (page index + a sample char known to render in the target font, optionally narrowed by
+ * the font's /BaseFont name) + the Unicode text the frontend wants to encode. It returns the
+ * charcode sequence the frontend can pass to {@code FPDFText_SetCharcodes}.
+ *
+ * <p>If the locator can't find a matching text fragment, or if the font can't encode some chars,
+ * the response reports which chars are missing so the frontend can fall back to Helvetica per char.
