As I understand, AnsiString and AnsiChar contain the environment type
of string (it can be ISO8859x, utf-8 etc...).
If that so, how can I know the size (in bytes) of AnsiChar ?
The size of the type "AnsiChar" is always one byte. It is impossible
to give the size of a generic "character" in a 1-byte string, because
in e.g. UTF-8 the size depends on the code point. To get the size of a
specific character, you can use
widestringmanager.codepointlengthproc(pchar,maxlookahead)
"maxlookahead" is the maximum number of bytes that routine is allowed
to check to find the complete character (e.g.
"widestringmanager
.codepointlengthproc(@ansistringvar[3],length(ansistringvar)-2)"). It
seems this routine has not yet been implemented for the Windows
widestringmanager though.
