Python: escaping issue with ujson

I am using ujson to convert dictionary to json. w开发者_运维百科hen I run the following line:

ujson.dumps({'key':'val\1'})

I get the following result:

[{"key": "val\\1"}]

while I expect/want it to be:

[{"key": "val\1"}]

any idea?

There is no problem, that's what repr looks like for this value. It is \1.
