safedict_simple.txt prefixed with garbage

Great project! Two minor problems with safedict_simple.txt when I tried downloading it and then viewing it using "less" on Linux:

The file starts with a whole bunch of null characters (^@).

The first word is nonsense (I think!): "edlessly".

Inspect safedict_simple.txt with less or another byte-aware viewer to confirm the leading null characters and the first entry. Clean the file's beginning and verify the intended first word from the project's available dictionary data; done means the file opens without prefixed garbage and starts with the correct entry.
