In fact users want to deal with "decently coded characters" and not with
"cryptic bytes some of which together are representing a character". (e.g.
when doing MyChar := MyString[1]; )
I think of Unicode text as a stream of Unicode characters in some
format. I trust that functions that deal with the string Copy, Length,
Find, etc., know how to handle it.
Right.
When doing:
MyChar := MyString[1]
appropriate function retrieves first unicode character, regardless of encoding.
This is just wrong :-(
MyString[1] accesses the first element of the *physical* character
array, regardless of any encoding. Also Length returns the array size,
not the number of *logical* characters in it.
Whether it's utf8, utf16, utf32 or any other future encoding the code
should work the same.
Very new functions are required for dealing with *logical* characters,
in every MBCS encoding.
