Java map returns null for current key

I have a very unusual problem.
Basically, I am trying to get the value associated with a key from a string map to strings.
I know that the key that I use is present; I use the same line that I used to enter it!

I print statements all over my code, and this is the case when I have ... Here is my characterDictionary

{thusChar=∴, spaceChar= , plusChar=+, equalsIndent=#, multiplyChar=×, equalsChar==, newlineChar=\n, divideChar=÷, subjectChar=:, variableIndent=@}

The most recent "variableIndent" key is the problem!
Here is the code ...

System.out.println  (   characterDictionary.get("variableIndent") );

which incorrectly displays: null

I checked, double checked and tripled my code.
There is no difference between the "variableIndent" key and the string argument characterDictionary.get("variableIndent"), but it behaves as if this key were missing.

I can guarantee that this key is present, and that the two lines are identical.
All other elements (those that I checked, about 3 so far) of the dictionary are extracted as usual. Why does "variableIndent" play with the value "@" with it?

You may notice that the dictionary contains non-ASCII characters, such as "thatChar". Could this be related?

Thanks
(This seems like a very simple and trivial problem, as if I made some kind of pathetic stupid mistake, but still I just can't solve it!)
