Robert Meyer updated FOP-2494:
------------------------------
Comment: was deleted
(was: I've been investigating this and have found the method we were using to
identify the number of character names in the post table was flawed. In the
case of the UbuntuMono-R.ttf font there are 1296 characters. 258 of these come
under the standard encoding whereas everything else should have an associated
name in the table. Unfortunately what we were doing was to read the post table
and use the glyph ID array to determine how many of those are greater than 258
by looping through them. The problem here is the fact that the indexes aren't
necessarily in a complete order. Therefore although we may count only 1046
characters that are greater than 258, the index array may do the following:
1,2,3,5,6,7,9,10,11,12...etc
The maximum glyph ID in this case is 1315, which minus 258 is 1057. As such a
fix for this will be to set the size of the Strings array (and subsequently
read) upon the maximum glyph index taken from that set. It's a fairly simple
fix and will post a patch and commit after I've done some further testing
tomorrow.)
