    a utility that creates a range item for an entire index
    
    Parameters:
    
    indexOffset - where the index is
    
    Returns:
    
    a range item representing the entire index
  - getCID
```
public byte[] getCID(String fontName)
```
    get a single CID font. The PDF architecture (1.4) supports 16-bit strings only with CID CFF fonts, not in Type-1 CFF fonts, so we convert the font to CID if it is in the Type-1 format. Two other tasks that we need to do are to select only a single font from the CFF package (this again is a PDF restriction) and to subset the CharStrings glyph description.
