thanks for your feedback! I thought about your comment a bit.

Your reasoning makes most sense in the context of object-oriented
programming languages (where you have an object and a set of methods
defined to operate on it). However, the crucial difference here is that
we don't have different object types, but always either strings of
characters or two codepoints, and the classification by type
(character, utf8, etc.) only helps when you study the library
structure, but not when using the API itself. Given the number of code
units is small, you can still quickly see which function belongs to
which source file.

The discussed API-change is part of a bigger "plan" that will however
not come intro fruition until after version 1 is released. Until then,
though, the API should be in its final form, as I don't want to impose
any API-changes after the first release, except when it really brings
dramatic improvements.

The strongest point for easier-to-read function names is that code is
written only once and read many times (ideally). So functions you can
"read" easier always win against functions that follow a stricter
structure and may be easier to program with.

With best regards
