Chinese characters
Phonetic loan characters, jiǎ jiè (假借), or characters that borrow a radical from other characters because they sound similar, not because they have the same meaning. These are called rebuses, or pictures/letters/numbers/symbols that are used to represent a word with the same pronunciation. For example, someone writes the sentence, "I'll see you tonight" as "⊙ L C U 2nite". Sometimes, a new character is made for the original word to not have any confusion between the different words.
