Field	Purpose
`CodePoint`	Unicode scalar value that could not be mapped; surrogate pairs are combined before being reported
`FontName`	Name of the font that would have drawn the code point as .notdef tofu
`Script`	Script classification for the code point, such as hfsCJK or hfsArabic
`SuggestedFonts`	Comma-separated list of the installed fonts the fallback engine suggests for this code point

Collect findings live through the OnUnresolvedGlyph event, or poll GetUnresolvedGlyphs after EndDoc; the recorder underneath de-duplicates repeat offenders
AnalyzeUnresolvedGlyphs checks a whole string against a primary font before you draw, handing back one record per unique failing code point and font pairing
Use Script to group findings by writing system, and SuggestedFonts to pick out a fallback font for the next run
