Is it correct to say that when I intend to always use
the spellcheck.q parameter I do not need to specify a
queryAnalyzerFieldType in my spellcheck searchComponent,
which I define in solrconfig.xml?
Given the limitations of the SpellingQueryConverter laid
out in the thread referred to above, it seems you want to
use the spellcheck.q parameter for anything but what can
be encoded in ASCII. Is that true?

Thanks for clarifying.

Yes, that is correct.
Even if a queryAnalyzerFieldType is not specified and your query uses q,
then WhitespaceTokenizer is used by default.

Umm, no actually. SpellingQueryConverter was written for a very simple
use-case dealing with ASCII only. But there is no reason why we cannot
extend it to cover the full UTF-8 set.
I'm sorry I forgot to follow-up on the old thread where you and Jonathan
posted a regex that should work. Can you please open an issue and if
possible, give a patch?
