It is not proper to encode English, French, ..., text that is eventually
rendered using small capital glyphs using the characters U+1D00 ᴀ LATIN
LETTER SMALL CAPITAL A and friends. One should use the "regular"
letters, either uppercase (e.g. in acronyms and such) or lowercase (e.g.
at the beginning of chapter) as appropriate. One way to choose between
uppercase and lowercase is to consider what happens if only the
uppercase and lowercase glyphs are available. The fact that those
character occurrences are intended to be rendered using small cap glyphs
does not change their identity.
Conversely, the identity of the LATIN LETTER SMALL CAPITAL characters is
closely connected to IPA, UPA and, more generally, phonetic texts.
This is what TUS 4.0 is saying page 171, under "Typographic variants".
