Hi,

NOTA BENE:

The next upload is kind of special so best save the old tex tree if you update.

Indeed. The following

\normalizefontwidth \FontA {ABCDEF} {\textwidth} {SerifItalic}
\starttext
  \FontA ABCDEF
\stoptext

fails with:

Tex error       > tex error on line 1 in file G:/Projects/Testing/bad.tex: Extra \else

\endgroup \always \edef \normalizedfontsize {37.77924pt=\zeropoint \bodyfontsize

<macro> \typo_normalizers_size
    #1#2->\dimexpr {#1\b_typo_normalizers }=\zeropoint \bodyfontsize \else
    \luaexpr {\number \dimexpr 10pt\relax *\number \dimexpr #2\relax /\number #1\b_typo_normalizers }\scaledpoint \fi \relax

    }}\definefont [\strippedcsname #2]
<line 3.1>
    \normalizefontwidth \FontA {ABCDEF} {\textwidth} {SerifItalic}

1 >>  \normalizefontwidth \FontA {ABCDEF} {\textwidth} {SerifItalic}
2     \starttext
3       \FontA ABCDEF
4     \stoptext
5
I'm ignoring this; it doesn't match any \if.
