It looks like: (1) We still have differences in SVG after turning this on. (2) FontCustomPlatformData::fontPlatformData is asserting because m_fontReference is null when running e.g., 'svg/W3C-SVG-1.1/animate-elem-03-t.svg' Will investigate further.
Debugging further, it looks like the buffer generated by convertSVGToOTFFont may be different in some way. If I pass this buffer through the Windows AddFontMemResourceEx method, it fails. However, the original code path works.
It appears that only font data produced by the ENABLE(SVG_OTF_CONVERTER) code path in CSSFontFaceSource.cpp suffer from this issue (convertSVGToOTFFont).

Different than what? By "original code path," do you mean "with the converter off?"
