Subject: [ruby-core:66812] [ruby-trunk - Bug #10593] Emoji is been	considered as comment

Issue #10593 has been updated by Yui NARUSE.


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 '#'.

| U+0023 U+20E3 | \x23\xE2\x83\xA3 |

```ruby
class Hash
  alias #������ to_hash
end
```

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

current workaround:

```ruby
class Hash
  alias :"#������" to_hash
end
```
