I believe I saw somewhere that in D a char was not neccesarrily the same as an ubyte because chars sometimes take more than one byte,
In D, a `char` is a UTF-8 code unit. Its size is one byte, exactly and always.
A `char` is not a "character" in the common meaning of the word. There's a more specialized word for "character" as a visual unit: grapheme. For example, 'Ä' is a grapheme (a visual unit, a "character"), but there is no single `char` for it. To encode 'Ä' in UTF-8, a sequence of multiple code units is used.
so since a string is an array of chars, I thought length behaved like walkLength (which I had not seen), in other words, that it simply returned the amount of elements in the array.
The elements of a `string` are (immutable) `char`s. That is, `string` is an array of UTF-8 code units. It's not an array of graphemes.
A `string`'s .length gives you the number of `char`s in it, i.e. the number of UTF-8 code units, i.e. the number of bytes.
