Add an exception to the conversion of "missing character" warnings into errors. The PGF package deliberately uses the dummy font "nullfont" to suppress output. Therefore, warnings about missing characters in "nullfont" are really only warnings. Also updated the comment: "Missing character" warnigns are especially widespread in XeTeX/LuaTeX but can also happen with "classical" 8-bit TeX. Feel free to port this to branch.
