Description

Unicode is been considered as comment.

Unicode Bytes
U+0023 U+20E3 \x23\xE2\x83\xA3
class Hash
  alias #️⃣ to_hash
end

when you require or load this file, will result in: syntax error, unexpected end-of-input.

current workaround:

class Hash
  alias :"#️⃣" to_hash
end

Background: https://github.com/sferik/active_emoji/pull/8

Thanks in advance <3.

It is spec.

At first the character is not Emoji.
The Unicode sequence "U+0023 U+20E3" consists of two Unicode codepoint:
U+0023 (NUMBER SIGN, '#'), and U+2E03 (COMBINING ENCLOSING KEYCAP).
Even if your environment shows the character as Emoji, it is not always an emoji.

And as above sequence, the character is considered as a variant of '#'.
