Variant 1:
\setuppapersize[A5,landscape]
\setuppagenumbering[location=none]
\startsetups [pagenumber]
\doifoddpageelse
{\cldcontext{"\letterpercent d",(\pagenumber+1)/2}}
{}
\stopsetups
\setupheadertexts [\directsetup{pagenumber}]
\starttext
\dorecurse{10}{\samplefile{knuth}}
\stoptext
Variant 2:
\defineexpandable[1]\DwarsliggerNumber
{\cldcontext{"\letterpercent d",(#1+1)/2}}
\defineconversion [dwarsligger] [\DwarsliggerNumber]
\setuppapersize[A5,landscape]
\setupuserpagenumber[numberconversion=dwarsligger]
\setuppagenumbering[location=none]
\setupheadertexts [\doifoddpageelse{\prefixedpagenumber}{}]
\starttext
\dorecurse{10}{\samplefile{knuth}}
\stoptext
