Aspell and French

["Paul Breeze" <dmarc-noreply@xxxxxxxxxxxxx> (Redacted sender "paul.breeze" for DMARC)]

Dear Carl
Further to my previous question, if I set the French dictionary as the 
default in the U2 registry, should I be able use ASPLGB to invoke the UK 
version?  I have tried it and it does not seem to work, so I assume not, 
but can you confirm?

Thanks

Paul
