How to Print Unicode Character U-1F4A9 'Pile of Poo' Emoji

How to print unicode character U-1F4A9 'pile of poo' emoji

Unicode code points with more than four hex digits must be enclosed in curly braces:

puts "\u{1f4a9}"
# => br>

This is pretty poorly documented, so don't feel bad about not figuring it out. A nice thing about the curly brace syntax is that you can embed multiple code points separated by spaces:

puts "\u{1f4a9 1f60e}"
# => br>

Of course, since Ruby 2.0, UTF-8 has been the default encoding, so you can always just put the emoji directly into your source:

puts "br># => br>

How to visualize my ruby program which simulates the growth of a tree?

I ended up using a combination of iGian and anquegi's answers (THANK YOU!).

You can try the game out at: https://repl.it/@benisburgers/OrangeTree

How to count the correct length of a string with emojis in javascript?

1. str.length gives the count of UTF-16 units.

2. Unicode-proof way to get string length in codepoints (in characters) is [...str].length as iterable protocol splits the string to codepoints.

3. If we need the length in graphemes (grapheme clusters), we have these native ways:

   a. Unicode property escapes in RegExp. See for example: Unicode-aware version of \w or Matching emoji.

   b. Intl.Segmenter — coming soon, probably in ES2021. Can be tested with a flag in the last V8 versions (realization was synced with the last spec in V8 86). Unflagged (shipped) in V8 87.
