enough to include caps and their accents.
winDescent non-negative integer Descender value for Windows.
Corresponds to the OpenType OS/2 table usWinDescent field.
‘usWinDescent is computed as the −yMin for all characters in
the Windows ANSI character set. usWinDescent is used to
compute the Windows font height and default line spacing.
For platform 3 encoding 0 fonts, it is the same as −yMin.
Windows will clip the bitmap of any portion of a glyph that
appears below this value.’ Thus, winDescent should be large

g, p, q, and y.

table name ID 21. ‘Used to provide a WWS-conformant family
name in case the entries for IDs 16 and 17 do not conform to
the WWS model. (That is, in case the entry for ID 17 includes
qualifiers for some attribute other than weight, width or
slope.) […] Examples of name ID 21: “Minion Pro Caption” and
“Minion Pro Display”. (Name ID 16 would be “Minion Pro” for
these examples.)’

the OpenType name table name ID 22. ‘Used in conjunction
with ID 21, this ID provides a WWS-conformant subfamily
name (reflecting only weight, width and slope attributes) in
case the entries for IDs 16 and 17 do not conform to the WWS
model. […] Examples of name ID 22: “Semibold Italic”, “Bold
Condensed”. (Name ID 17 could be “Semibold Italic Caption”, or
“Bold Condensed Display”, for example.)’ For name IDs 16 and
17, see the entries for preferredFamilyName and preferredSubfamilyName,
respectively.
