I am having a problem using mongoimport when the data value is a full stop.
It appears the full stop "." is translated to 0 during the insert

Example file
"name","value"
"Hello","."

Import command
mongoimport --db test --collection dottest --type csv --headerline --file world.csv

Result on MongoDB
> db.dottest.find();

{ "_id" : ObjectId("4d67d6cb4e6aea4032d2230e"), "name" : "Hello", "value" : 0, "field2" : "e\"" }

It seems like the "." is being treated as two fields, the first having value 0 and the second "e\""

I don't have this problem if I insert from a Mongo session
db.dottest.save(

{"name":"Hello","value":"."}

);
works fine

Or if I use mongoimport and the full stop appears with other text "Hello","Mr." will load fine
