I like how the pattern matching here improves readability.
But, as I left a comment, if expression should be preferred for boolean values.

Good!
Have a good day. Thank you.

Looks good.

P.S.

https://doc.rust-lang.org/std/primitive.bool.html#method.then_some

I read bool's two method implementation: bool::then and bool::then_some, whose behaviors are subtly different. The key thing is here: the former lazily evaluated the passed closure while the latter one evaluates passed value eagerly. In this case, bool::then is a proper choice because we don't to evaluate the function only when take_char is true. (And you made the right decision, I think)
