mvn install fails with "error: unmappable character for encoding UTF8"

[gigafone]

I clone the repository and checkout master (currently the same as the 'release_5.3.0' tag).

When I run mvn install -e -X I get:

The cause was the phrase "Count–min sketch" which contains an en dash; e.g. –. It looks like it was pasted into the code incorrectly, breaking UTF-8 encoding.

Here's a git patch:
