Its text still can't be selected, searched or copied without a `/ToUnicode`, Courier New and other faces whose numbering isn't confirmed aren't read this way, and Arial and Times New Roman glyphs past the first 258 (Cyrillic, Greek) and every other font's characters the substitute lacks still fall back to the CID taken as one of the substitute's glyph indexes, an unrelated glyph (#3529, #5726)"
