fallbacks for characters

fallbacks for characters

[Thomas A. Schmitz]

Hi all,

the answer to this one may be completely obvious, but I haven't found  
anything: I know we can define fallback fonts in mkiv, but is it  
possible to define fallbacks for single characters. Let's take 0x0113,  
"emacron." Is it possible to define "if character is present in  
current font, use it; else \buildtextaccent\macron e" ?

\definefontfallback [myfallback] [Fallbackfont] [0x0113]
[force=yes|no,check=yes|no]

% check : only replace when present in replacement font (default: no)
% force : force replacent even when basefont has glyph  (default: yes)

Wolfgang, thanks for your answer! But if I understand  
definefontfallback correctly, this will define a replacement font -  
that's not what I want. I want to take glyphs from the same font,  
either the matching glyph or a composite one.

you can falback on the fotn itself then

but, did you try the compose=yes feature?
