Yes, it is a known fact that this is a weakness of UTF-8.
Maybe you should say its a feature.
Consider transforming the string to UTF-16, UTF-32 or even an internal
datastructure before doing the random access.
This has been already discussed here at any length, resulting in the
knowledge that this also does not help in all cases (as all Unicode
variants allow for extended codes).
Delphi XE and mse use UTF-16 by default as a (in most cases appropriate)
compromise. I suppose, FPC and Lazarus will follow at some point in
time, making these discussions less stringent.
A decent smart "indexer" class with appropriate enumerator/iterator-like
compiler-magic syntax might help until then and is a lot nicer than the
old-fashioned myString[i] notation anyway, on top of being compatible
with any future string implementations.
