Thanks for the suggestion Paulo, much appreciated. Unfortunately those
changes didn't make a difference as far as the symbols appearing. Just to
clarify what I did:

I edited iTextSharp\text\pdf\DocumentFont.cs for v4.0.8.0 and made any
changes as suggested that had to do with diffmap. This included the
following within their respective methods (let me know if I should post
entire file):

private IntHashtable diffmap;

if (diffs != null) {
diffmap = new IntHashtable();

if (c != null && c.Length > 0) {
uni2byte[c[0]] = currentNumber;
diffmap[c[0]] = currentNumber;
}

if (diffmap != null) { //widths for differences must override existing ones
e = diffmap.ToOrderedKeys();
for (int k = 0; k < e.Length; ++k) {
int n = diffmap[e[k]];
widths[n] = bf.GetRawWidth(n,
GlyphList.UnicodeToName(e[k]));
}
diffmap = null;
}

All the other changes had nothing to do with diffmap, so they weren't
changed (I wouldn't have been able to change most of those others anyhow, as
there were changes in variables to overridden functions.

I rebuilt the project successfully (of which the new dll is of course
included in my project), but the problem remains. Setting
BaseFont.DirectTextToByte to true still solves the problem, but I realize I
shouldn't do that.

Is there something simple that's missing in order to make this work?

Thanks much,

- Stew

You can't replace one with other. See
http://itextsharp.cvs.sourceforge.net/viewvc/itextsharp/itextsharp_new/iText
Sharp/text/pdf/DocumentFont.cs?view=diff&r1=text&tr1=1.13&r2=text&tr2=1.9&di
ff_format=h and replace only the code related to the variable diffmap.
