Use less exotic unicode chars
Use less exotic unicode chars

The characters used before were in the private-use section had surrogate
chars. This led to issues with some python utf8 decoder implementations
resulting in the error

```
UnicodeEncodeError: 'utf-8' codec can't encode characters in position
13-20: surrogates not allowed
```

This uses more normal utf8 characters that should hopefully work
everywhere while still exhibiting issues decoding to ascii.
