Currency signs are not recognized

[stefanvanherwijnen]

For example, when running ocrs against:

https://pngimg.com/d/euro_sign_PNG21568.png
https://t4.ftcdn.net/jpg/05/83/55/69/360_F_583556911_o9Si9XG8wXVUF9eX5qnwe7pepIeusWJh.jpg

results in empty output:

~/Downloads
❯ ocrs "eurosign.png" 


~/Downloads
❯ ocrs "dollarsign.jpg"

In these particular images, the issue is the large size of the single character. In a screenshot of text with a smaller font, like this:

The output is "This is some text with a dollar $ and euro ? sign". The set of characters supported in the default model is 0123456789!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~EABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz, so this includes the dollar sign but no other currencies.

Thanks, makes sense. However, for the following invoices it doesn't work either (also the % sign doesn't seem to be recognized):
