I lack some understanding of TeXmacs internals concerning fonts management, so I was not able to provide a clean patch for that bug. However, here are some findings that may help Joris and David to fix this bug.

1) When math-font is set to Euler New Roman, the definitions of the symbols in the virtual font 'negate' (the file negate.vfn) are used in place of the symbols in the virtual font 'misc'. For instance, if you type a \ldots symbol (". ."), which is the 7th symbol defined in misc.vfn, you will see a \nni symbol, which is the 7th symbol defined in negate.vfn. And so on: the nth symbol in misc.vfn is drawn like the nth symbol in negate.vfn.

2) A similar swapping is taking place between negate.vfn and long.vfn: the nth symbol in negate.vfn is drawn like the nth symbol in long.vfn.

3) So it seems that each symbol definition is shifted to the other file definition. And if you comment one of the previous lines before the virtual fonts definition in font-math.scm (for instance line 270), the virtual fonts symbols are now correctly represented (though I doubt this is the proper way to fix that bug).

When using the Euler New Roman math fonts with TeXmacs, some characters
appear incorrectly. In particular, the $\ldots$ character appears correct
when using Roman, Concrete or Adobe but when the math font is switched to Euler
New Roman it looks like a "not contains as an element" sign, that is a
negated reversed version of $\in$. Similar problems occur with $\cdots$
and $\hdots$, looking like the negations of $\cong$ and $\subset$.
