Re: Investigating: LATIN CAPITAL LETTER J WITH DOT ABOVE

[Ernest Cline]

Well, in the event that Unicode ever does add  DOTTED J to go with
DOTLESS J, I sincerely hope that it does not follow the example of
DOTTED I and DOTLESS I.  It would have been better in my opinion
to have encoded upper and lower case forms of both characters
separate from the ordinary I.  That would have placed language
specific burdens not on the casing algorithm of Unicode but on the
transfer of data from legacy character sets.  It's probably too late
to change this for the I, but hopefully this can be avoided for J if
a distinct dotted J  character is needed.
