title: Why shouldn't I use weird Characters in code/HTML documents?
body: <p>I'm wondering if it's a bad idea to use weird characters in my code. I recently tried using them to create little dots to indicate which slide you're on and to change slides easily:</p>
  
  <p><img src="https://i.stack.imgur.com/rcrJA.png" alt="enter image description here"></p>
  
  <p>There are tons of these types of characters, and it seems like they could be used in place of icons/images in many cases, they are style-able and scale-able, and screen readers would be able to make sense of them. </p>
  
  <p>But, I don't see anyone doing this, and I've got a feeling this is a bad idea, I just can't decide why. I guess it seems too easy to be true. Could someone tell me why this is or isn't okay? Here are some more examples of the characters i'm talking about:</p>
  
  <p>↖ ↗ ↙ ↘ ㊣ ◎ ○ ● ⊕ ⊙ ○　 △ ▲ ☆ ★ ◇ ◆ ■ □ ▽ ▼ § ￥ 〒 ￠ ￡ ※ ♀ ♂ &amp;⁂ ℡ ↂ░ ▣ ▤ ▥ ▦ ▧ ✐✌✍✡✓✔✕✖ ♂ ♀ ♥ ♡ ☜ ☞ ☎ ☏ ⊙ ◎ ☺ ☻ ► ◄ ▧ ▨ ♨ ◐ ◑ ↔ ↕ ♥ ♡ ▪ ▫ ☼ ♦ ▀ ▄ █ ▌ ▐ ░ ▒ ▬ ♦ ◊ </p>
  
  <p>PS: I would also welcome general information about these characters, what they're called and stuff (ASCII, Unicode)? </p>
