TypeError: unsupported format string passed to Text.__format__

This error occurs when you try to use an unsupported format string with the `format()` method on a text object.

For example, consider the following code:

text = "Hello, world!"
print(text.format("John"))

This code will raise the `TypeError` because the format string `"John"` is not supported by the `Text` object.

To fix this error, you should use a valid format string that is supported by the `Text` object. Here is an example:

text = "Hello, {}!"
print(text.format("John"))

This code will output: `Hello, John!`
