There is still an issue when one work in the document for the currency column. The text is overlapped. I'm pushing this bug forward to 5.0.4 and updated more test cases to the support drive.

Still having difficulty fixing this issue for all the test cases. It would appear that the font size > 1 and a negative Tc value is the root of the problem. My current path fixes the layout for the attache document but there are still some problems with it for other documents.

Duplicate issue.

Finally found the root of this spacing issue. A CID font can define a W or DW key in the font dictionary that can be used to override font widths define by the font program. In the problematic PDF's the glyphs where layed out using the W or DW values.
It also appears that a DW or default width should only be respected if the W array is absent. The fix is a lot cleaner then previous attempts. Needs to pass QA but I'm pretty confident this one won't be opened again.
