Many thanks to those who responded to me earlier. I have looked further into this, but I still have a problem.
In the locales_target table, the French for February is stored as février, but if I put the French word for February (février) into the database in a node (marked as French), it is stored as février not as février.
Can anyone shed any light on this?
Many thanks indeed.
