Hello

For reference: Here is the ConTeXt way of entering a long text-Index, which works with lmtx:

\starttext
\m{F_{\text{long Index}}=m_{\text{long Index}}a}
\stoptext

Sorry for the noise. (Perhaps a change correlated to the prime discussion...)

Hello list

Sorry to ask again. What do I miss in following MWE?

\starttext
\m{F_{\rm longIndex}=m_{\rm longIndex}a}
\stoptext

The index longIndex overlaps the following characters "=" and "a" when processed with lmtx. No problems with mkiv.

Thanks for your help

Hello

Following MWE produces strange output in latest LMTX. mkiv (also latest) output is ok.

\usetypescript[palatino]
\setupbodyfont[palatino,11pt]
\starttext
\m{F_{\rm longIndex}=m_{\rm longIndex}a}
\stoptext

The spacing in the index is wrong.

What am I missing?

Thanks in advance
Christian
