Support emojis with skin tone

[Tyriar]

From @pcgeek86 in microsoft/vscode#129470

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.58.2
• OS Version: Windows 10 Build 21387

Steps to Reproduce:

1. Run Python 3 in VSCode Integrated Terminal
2. Paste code below

mystr = ''
for x in [0x1F442, 0x1F3FC]:
  mystr += str(chr(x))

print(mystr)
print('👌🏻')

Here's how VSCode Integrated Terminal renders it:

Here's what it (correctly) looks like in Microsoft Terminal (albeit it has a whitespace issue):

Expected Result

Emojis with skin tones should be rendered with the specified string.

Actual Result

Emojis with skin tones are rendered as two separate characters.

This is related to handling of Extended Grapheme Clusters. See this comment about how Domterm handles clusters.

Does this issue ticket cover other similar issues like https://stackoverflow.com/q/77425006/11107541 or should a new issue ticket be raised for that?

I believe this can be closed, now that PR #4519 has been merged.

You need to enable the unicode-graphemes addon.

@Tyriar Does VS Code yet have an issue ticket about enabling the unicode-graphemes addon? If you create one / know of one, can you please ping me with it?
