Also, Acrobat 4.0 and earlier viewers incorrectly allow substitution fonts,
such as TimesNewRoman and ArialMT, to be specified without FirstChar,
LastChar, Widths, and FontDescriptor entries.
Table H.3 shows the complete list of font names that are accepted as the
names of standard fonts. The first column shows the proper one (for ex-
ample, Helvetica); the second column shows the alternative if one exists
(for example, Arial).
5.5.3, “Font Subsets”
63. For Acrobat 3.0 and earlier viewers, all font subsets whose BaseFont
names differ only in their tags should have the same font descriptor values
and should map character names to glyphs in the same way; otherwise,
glyphs may be shown unpredictably. This restriction is eliminated in
Acrobat 4.0.
5.5.4, “Type 3 Fonts”
64. In principle, the value of the Encoding entry could also be the name of a
predefined encoding or an encoding dictionary whose BaseEncoding
entry is a predefined encoding. However, Acrobat 4.0 and earlier viewers
do not implement this correctly.
