Method Details
- isCodePointPrintable
  
  public static boolean isCodePointPrintable(int codePoint)
  
  Checks if a code point is printable. If false, it can be safely discarded at the rendering stage, else it should be replaced with the replacement character, if a suitable glyph can not be found. NOTE: This should only be called after a character has been shown to be NOT present in the font. It can not be called beforehand because some fonts contain private area characters and so on. Issue#588.
  
  Parameters:
  
  codePoint -
  
  Returns:
  
  whether codePoint is printable
- isSafeFontCodePointToPrint
  
  public static boolean isSafeFontCodePointToPrint(int codePoint)
  
  Whether the code point should be passed through to the font for rendering. It effectively filters out characters that have been shown to be problematic in some (broken) fonts such as visible soft-hyphens.

  whether all characters are printable
- parseIntegerOrNull
