As a starter I've added some convenience methods to the TrueTypeFont class in the trunk http://svn.apache.org/r1599786

> For certain PDF documents (such as the one attached) 
> the character/string widths (as obtained e.g. by the 
> PDFont.getStringWidth method) are not returned 
> correctly, i.e. they appear to be correct for punctuation 
> characters but are zero for alphanumeric characters.  
> It seems as if these alphanumeric characters are NOT 
> within PDFont.firstChar and PDFont.lastChar in the 
> Type 1 font.  The method therefore attempts to obtain 
> the font widths from the AFM (font metric) file, but fails 
> (silently) with a 'resource is null' logline message.
> (Note that this problem doesn't seem to occur with Type 
> 1 fonts in other documents.)
> A more detailed discussion regarding this issue can be 
> found in this link:
> http://sourceforge.net/forum/forum.php?
> thread_id=1260349&forum_id=267205
> Thanks in advance for any help that can be obtained,
> Tam
