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

"maxlookahead" is the maximum number of bytes that routine is allowed  
to check to find the complete character (e.g.  
.codepointlengthproc(@ansistringvar[3],length(ansistringvar)-2)"). It  
seems this routine has not yet been implemented for the Windows  
widestringmanager though.
