%--------------------------------------- the redefinitions

% A text command invoked in PDF-sttings must be "string-OK".
% Here a text command is "string-OK" if both:
% - fully expandable, and
% - comprised only of "Unicode-OK" glyphs.
% Here a glyph is "unicode-OK" if either:
% - representable as a single Unicode character, or
% - well-substituted with a single Unicode character.
% When the original definition of an aj-macro command is not string-OK
% (marked as <!>), then the command must be redefeind.

%%<!> \ajTsumesuji<var>{<string>}
%%<!> \ajTsumesuji*{<string>}
% Simply expands to the string.
\pxhy@DeclareMacroVar{Tsumesuji}#1#2{#2}{}
% \ajTsumesuji* takes only one argument.
\pxhy@def{Tsumesuji@V}#1{#1}

%-----------------------
% Enclosed letters

% None of the aj-macros for enclosed letters are fully expandable,
% so they all must be redefined.
% The glyphs for enclosed alphabet and kana letters are Unicode-OK
% (\ajMaruKata{1} is U+32d0(㋐), and \ajMaruHira{1} fallbacks to plain
% あ letter), but some of those for enclosed numbers are not Unicode-OK
% (\ajMaru{51} does not have a good fallback), and thus should give an
% alternative fallback string (\ajMaru{51}→“51”).
% Note: for some enclosed numbers, glyphs with different enclosure are
% used as fallback (e.g. \ajKuroMaru{21}→“㉑)”.
