At now LibreOffice calc add non-breaking space only for numbers separator, so number 1000000 is formatted as "1 000 000" - it's ok.
But when we add symbols to number, they are separated by breaking space symbol, for example in EUR German format "1000000" is represented as "1 000 000 €" instead of "1 000 000 €", so in cell this number can be splitted to 2 lines, like:
1 000 000
Will be good to add all spaces from Format code as non-breaking space, or provide special symbol for insert non-breaking space in Format code.
Sounds reasonable -> NEW.
