2) Again, the charater-as-class also means that the speed with wich we can
create and destroy (and manipulate) a string is a lot slower.

Hi,
The online RTL documentation (HTML) doesn't have the usual stylesheet enabled.

Actually the fpdoc.css stylesheet is missing.

Yes, but most proposals here about a TCharacter are a bit overkill. In

a Unicode point of view, unicode focuses its power in the text, so
locale is important in context operations and collations.
See my other post above.
