Unicode or ASCII chars?

[UberJason]

Hi there,

This is more of a question than an issue, as I haven't had a chance to try this out yet - just wondering if your library is able to recognize unicode chars, such as ♠️♦️♥️♣️, or ASCII chars, such as ♠♥♦♣ ? Maybe if I supply any of these as part of the recognizable characters set and/or do training with different images?
