The screen shot comparing rendered PDF generated by PDFBox and actual text with similar font rendered in Microsoft Notepad. Notice that in left most red oval have one glyph missing under base line character compare to left most green oval being rendered in Notepad.
The second to left most oval contain some overlap rectangular character due to it fail to render glyph properly. The right most green oval illustrate how Notepad render it.
