Hi, I'm using a font (only in the headers) that doesn't have Spanish characters. What I want is for it to automatically replace the text with a custom font when I type it in the header.

Sample: \chapter{Peru} ==> Peru (replace ú with u)

=========

\definefont[typographercaps][name:typographercaps*default at 35pt]

\setuphead
  [chapter]
  [align=middle,
   color=darkred,
   number=no,
   style=\typographercaps]

\starttext

\dorecurse{5}{\chapter{ann chapter} \input knuth}

\stoptext
