| - Test character type with: | |
| - [`isLetter()`][ref-isletter], covers many alphabets (the Lu, Ll, Lt, Lm, and Lo categories in unicode) | |
| - [`isDigit()`][ref-isdigit], in range 0..9 (the Nd category in unicode) | |
| - `isLetterOrDigit()`, combines the previous two | |
| - [`isWhitespace()`][ref-iswhitespace], any whitespace character (the Cc, Zp, Zl, and Zs categories in unicode) |
I think this is the correct markdown format.
For about.md only, I think we can explain how it's implemented by specifying the unicode categories (that's how these functions work!)

I'm a bit confused about the way Kotlin implements Unicode as fixed-width 16-bit, so I'll ask for clarification on the forum before marking this ready for review.
