      Parameters:
      graphics - the graphics context to request additional rendering hints
      fontInfo - the font info object corresponding to the text run font

    • mapFontCharset

      String mapFontCharset(Graphics2D graphics, FontInfo fontInfo, String text)
      Map text charset depending on font family.

      Currently this only maps for wingdings and symbol font (into unicode private use area)

      Depending if the requested font is installed in the system, tbe mapped string varies:
      If the font is registered into the graphics environment the characters are mapped to the private use area. If the font is missing (and hence a AWT logical font is used), the characters are mapped to the corresponding unicode characters

      Parameters:
      graphics - the graphics context to request additional rendering hints
      fontInfo - the font info object corresponding to the text run font
      text - the raw text
      Returns:
      String with mapped codepoints
