Tilman Hausherr commented on PDFBOX-3061:
-----------------------------------------
Thanks... After that, I thought about that comment "todo: this method is highly
suspicious, the average glyph width is not usually a good metric" - indeed: the
space width can be smaller than the avg width, and it WILL BE if capital
letters are included in a font.
No changes in rendering in existing files.
