This is the important part which was missing in your original message -
you don't use Unicode specific types (UnicodeChar, UnicodeString,
UTF8String, etc.). As mentioned in my e-mail, my comment was primarily
related to using these types. Obviously, if you use a type which is
"transparent" from this point of view, everything is up to you.

Yes, the alternative notation solves that problem indeed.
