Yes, using characters from a mixture of fonts that have widths that do
not add up to multiples of each other just isn't supported by Gnus. To
do so would require a rewrite of the machinery that generates the
buffers, and gnus-summary-line-format would have to be obsoleted and
something new that uses display properties with align-to could be used.
So I'm closing this bug report as a "wontfix".
