+You have identified a gap in the social media market for very very short
+posts. Now that Twitter allows 280 character posts, people wanting quick
+social media updates aren't being served. You decide to create your own
+social media network.
+
+To make your product noteworthy, you make it extreme and only allow posts
+of 5 or less characters. Any posts of more than 5 characters should be
+truncated to 5.
+
+To allow your users to express themselves fully, you allow Emoji and
+other Unicode.
+
+The task is to truncate input strings to 5 characters.
+
+## Text Encodings
+
+Text stored digitally has to be converted to a series of bytes.
+There are 3 ways to map characters to bytes in common use.
+* **ASCII** can encode English language characters. All
+characters are precisely 1 byte long.
+* **UTF-8** is a Unicode text encoding. Characters take between 1
+and 4 bytes.
+* **UTF-16** is a Unicode text encoding. Characters are either 2 or
+4 bytes long.
+
+UTF-8 and UTF-16 are both Unicode encodings which means they're capable of
+representing a massive range of characters including:
+* English language text
+* Foreign language text
+* Historic text
+* Emoji
+
+UTF-8 and UTF-16 are both variable length encodings, which means that
+different characters take up different amounts of space.
+
+Consider the letter 'a' and the emoji '😛'. In UTF-16 the letter takes
+2 bytes but the emoji takes 4 bytes.
+
+The trick to this exercise is to use APIs designed around Unicode
+characters (codepoints) instead of Unicode codeunits.
