I don’t know how ConTeXt handles it internally, but placement to main
character differs with each letter:

  \starttext
    \doloopoverlist{\tf,\ss,\tt}
      {\bgroup\recursestring\doloopoverlist{\tf,\it,\bf,\bi,\sc}
        {\bgroup\recursestring\dorecurse{26}
          {\character{\recurselevel}̱ }\par}\egroup}
  \stoptext
