Ruby将十六进制转换为字符并打印（Unicode希伯来语）

Question

Hello I am working on a project that requires analysis of Hebrew characters.

I have a case like so

letter = case

         when (a[0] == "1") && (a[1] == "2"): "He ה"
         ...
         end

p letter 

=> "He ה"

I want to also print the Hebrew character from Unicode hex number (for He 05D4), like so:

letter = case
         when (a[0] == "1") && (a[1] == "2"): "\05D4 He ה" 
         ...
         end

p letter 

Desired output => "ה He ה"
Actual output => "\005D4 He ה"

Ruby 1.8.8. $KCODE = "u" is set above code.

What do I need to do? I have tried a few different things to no avail (eg, ['05D5'.hex].pack("C") ) => error char out of range

Thanks in advance.

The only problem is your debugging code. Kernel#p writes object .inspect , and that tries perhaps a bit too hard to show you internal structure.

Just use a real I/O method like puts and I think you will be fine.
