Ruby Unicode转义中的ASCII空格字符

Question

Doing some reading and came across this block of code on the topic of Unicode Escapes in Ruby:

money = "\\u{20AC 20 A3 20 A5}" # => "€ £ ¥"

I understand that in this ruby syntax, the actual spaces between the {} 's doesn't output an encoded space, that's the reason for the code point 20 but what I don't understand is why there's a code point 20 at the very beginning of the {} , right after the \\u\u003c/code> . No space has been output in the result and I copied it verbatim from the book.

Answer 1

It's not a 20 at the beginning, it's 20AC , which is the code point for € . The contents of the braces are a space separated list of codepoints (in hex format). 20AC is € , 20 is a space , A3 is £ and A5 is ¥ .
