“Space Yourself” ↦

There’s a lot more to spaces than that big key on your keyboard:

Spaces are [in the Unicode table], too. There’s the one with an agent good enough to have gotten it the biggest key on everyone’s keyboard, but there are many more: the very narrow hair and thin spaces, the super-wide en and em spaces, and a few others in between:

• Hair space
• Six-per-em space
• Thin space
• Normal space
• Four-per-em space
• Mathematical space
• Punctuation space
• Three-per-em space
• En space
• Ideographic　space
• Em space
