function PUCUUnicodeIsWhiteSpace(c:TPUCUUInt32):boolean; {$ifdef caninline}inline;{$endif}
begin
//result:=UnicodeGetCategoryFromTable(c) in [PUCUUnicodeCategoryZs,PUCUUnicodeCategoryZp,PUCUUnicodeCategoryZl];
 result:=((c>=$0009) and (c<=$000d)) or (c=$0020) or (c=$00a0) or (c=$1680) or (c=$180e) or ((c>=$2000) and (c<=$200b)) or (c=$2028) or (c=$2029) or (c=$202f) or (c=$205f) or (c=$3000) or (c=$feff) or (c=$fffe);
end;

case block will be better.

``` function PUCUUnicodeIsWhiteSpace(c:TPUCUUInt32):boolean; {$ifdef caninline}inline;{$endif} begin //result:=UnicodeGetCategoryFromTable(c) in [PUCUUnicodeCategoryZs,PUCUUnicodeCategoryZp,PUCUUnicodeCategoryZl]; result:=((c>=$0009) and (c<=$000d)) or (c=$0020) or (c=$00a0) or (c=$1680) or (c=$180e) or ((c>=$2000) and (c<=$200b)) or (c=$2028) or (c=$2029) or (c=$202f) or (c=$205f) or (c=$3000) or (c=$feff) or (c=$fffe); end; ``` case block will be better.
