Additional info

I tried the following famous terminals but all did not display the character as expected.

And I also tried several famous fonts but they did not help to solve this issue too.

Hi, thanks for opening this issue! I'm planning to do a large rewrite of the crate within the next 2 weeks. One of the features I'll be adding is the ability to more precisely customise the characters used for error output, so hopefully this issue can be resolved then.
