Yet another unusual take for the Orchid STL: Unicode codepoints aren't a part of the string library.

For the purposes of a high level language, the unit of text is a grapheme. Strings can be converted between Unicode and binary blobs. In a binary, indices address bytes. In text, indices address graphemes. For example, searching a string for a substring that consists of a single letter implies the added constraint that the letter must not have accents or other modifiers.

For storage and transfer optimization it's possible to discover the byte length of a string without converting it to binary
