Our base documents are stored in WPTools5 and I have a program that creates PDFs from them.
I started using CIDFontMode := wpCIDUnicode and that seemed good, but I have since found that with that option set, one of our bullet characters gets output wrong. The bullet appears to be a WingDings character 'l' in the source document, but with wpCIDUnicode set it show us as ó everywhere it's used.
I have to use the Unicode option for some of my output languages (Vietnamese in particular) and I can't find any way around having invalid characters when it's turned on.
I sent three sample files to the support email, but haven't heard anything for a couple of days, so if you need them again, let me know.
