But, is this really an issue? Street signs may be in two or more

name a multi-lingual area where a stopword in one language would be a
non-stopword in the other language?
"de" is "the" in Dutch, "of" in French - both (candidate) stopwords in
their own way, but you would want different rules for keeping or
omitting "de" in street names.
It also means "South" in Welsh, which you probably would not want to
omit in most cases.....
Is there an administrative area where both Welsh and Dutch or French are
used in street name signs? I would not expect so.
AFAIU, your suggestion wrongly assumes that only one language will be
used in a given region. And I think it should be based on
administrative regions, not necessarily countries.
I intended to suggest that each area would have a single "default"
language. Main reason is to select the correct stopword treatment in
the absence of explicit name:xx tags. In most cases roads are just
tagged with "name=*" - so this mechanism would define the mapping of
"name" to a language. Then you only need a single stopword treatment
for the language, which can be shared by all territories which use
that language.
Right, this suggestion should be a reasonable default, if it is
selectable by any admisitrative level (such as country, state, province
or municipality).
How would you represent an area that has multiple official languages
that can appear on street signs? I think that the OSM convention would
be something like this:
{ set mkgmap:lang:fi=yes; mkgmap:lang:sv=yes; }
or the (more tricky for our style rules)
{ set mkgmap:lang='fi;sv' }
Well, I assume that the maps produced by mkgmap are targeted to a
language (or ordered list of languages) chosen by the mkgmap user.
I do not think that it is always a reasonable assumption. Most areas in
Finland use Finnish as the primary official language. For some places or
streets in a Swedish-speaking area there could exist Finnish names, but
maybe the Finnish-speaking minority is so small that the signs are only
in Swedish. It could be more useful to have the street names in the same
language on the map as you have on the signs. Only if the street signs
displayed each language, it would make more sense to let the user to
override the primary language (name=* labels) at map translation time.
Similarly, when travelling in former Finnish-language areas that were
made part of the Soviet Union, it could be more useful to have the
current Russian names on the map, because the street signs would not be
in Finnish any more.
I can't imagine someone wanting all the languages in the map at the
same time. Can the Garmin format even handle that?
AFAIU, only the Garmin NT format (which mkgmap does not support) allows
you to define labels in multiple languages.
