+/**
+ * Charcode-encode helper for the v2 PDF text editor.
+ *
+ * <p>The frontend editor uses PDFium-WASM, which exposes {@code FPDFText_SetCharcodes} for writing
+ * 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.

+ * Probe: what can PDFBox actually do for font ENCODING on real-world PDFs. This is a diagnostic
+ * test (not a regression) - run with --tests PdfBoxFontEncodingProbeTest -i to see stdout.
+ *
+ * <p>Answers these questions:
+ *
+ * <ol>
+ *   <li>Type0/CIDFontType2 subset: can we add a new glyph not in the original subset? (no, encode
+ *       throws IllegalArgumentException).
+ *   <li>Type1: same question.
+ *   <li>TrueType: same question.
+ *   <li>Can we load a fresh TTF via PDType0Font.load(doc, file) and write text with it? (yes,
+ *       primary path).
+ *   <li>Round-trip via getFontStream / re-embed - can it rehabilitate Type3? (no - Type3 has no
+ *       FontFile* program at all).
+ *   <li>What fonts ship with PDFBox / fontbox? (only LiberationSans-Regular.ttf + AFM for the 14
+ *       standard fonts; CFF/Type1 binaries are NOT bundled - Standard14Fonts.getMappedFontName
+ *       redirects unmappable ones to LiberationSans).
