[r6rs-discuss] Case Folding

[Alan Watson]

The lower-case dotless i character is missing from the following 
sentence in section 1.1. of the HTML (but not the PDF) version of the 
libraries document:

   For Turkic characters I (#\x130) and (#\x131), char-foldcase behaves
   as the identity function; otherwise char-foldcase is the same as
   char-downcase composed with char-upcase.

Second, I think the case folding of characters required by the R6RS 
corresponds to applying the mappings with status C and S from 
CaseFolding.txt or the identity function if no such mapping exists 
(i.e., the "simple case folding" described at the top of that file). Is 
my understanding correct? Might this not be a more concise way to 
describe case folding?
