It is not (says the one who wrote the AI).
The issue of using String or a different type was carefully
investigated, and String was chosen mainly on the ground of usability
(f.e., when you read from a text file, you don't know if it is encoded
or not until you have read the BOM - would you read the BOM into a
String or an Encoded_String?)
This appears in the !discussion section of AI AI05-0137-1/05
Note that the AI carefully talks about "characters whose position
numbers correspond to the encoding".
An encoding is a way to store a character string in a more compact
manner, but it still represents a string of characters. Compare that
with packed arrays - that does not change the high level nature of the
array.
