In french, a street name Saint-Jacques would be abbreviated "St-Jacques".
As "Saint" is only a part of the word, putting Saint > St in the dictionary doesn't abbreviate it.
And since there is a lot of saints, i don't want to add all of them in my abbreviation dictionary.
It would be nice to be able to work with the "Saint" part only, with something like "Saint%" or "Saint-%" in the dictionary.
