I found that calling the soundex() changes the input string to capital. Even creating a deep copy cannot prevent the change.

My current solution is to create a new string then append the letters of input string to the new string one at a time, then use the new string as the input for soundex().

This fork has got it fixed : https://bitbucket.org/dhellmann/fuzzy Basically deepcopy doesn't work because strings are immutable in python but since the library internally makes a C call, it gets modified in place by C which should have not happened.
