John Hewson commented on PDFBOX-2843:
-------------------------------------
If you call font.getSpaceWidth() you'll get better values. Something like 250
is what you'd expect (i.e. 1/4em). This unit is is glyph space, so you can
convert it to user space using the text rendering matrix.
> widthOfSpace() appears wrong in TextPosition
