I have some text and want to know if a character is a Chinese character.

Using AppleScript, I know that the id of the character "用" is 29992.

http://www.unicode.org/Public/UNIDATA/Blocks.txt provides a list of ranges for each Unicode 'block'.

So, how should I test if the decimal number of character 29992 is in a range of hex numbers to determine what its 'block' is?

I'm suppose that I need to create a lookup table of the 'Blocks.txt' in AppleScript, with column 1 being the 'from' range, column 2 being the 'to' range and column 3 being the 'block name'.

What I still can't work out how to do is to either convert the decimal 29992 to a hex number and (somehow) test if it's in a hex range, or convert the 'from' and 'to' columns to a decimal value. I guess the latter would be easier for the comparison.

CJK Unified Ideographs seems to be 0x4E00 - 0x9FFF however I'm not sure if there are any subranges which should be accounted for.

set char_id to 29992

do shell script "tclsh <<< 'set test " & char_id & ";if {$test <= 0x9FFF && $test >= 0x4E00} then {puts 1;} else {puts 0;}'"
