åct. I don't know what it means yet, or how it's related to its root word...I'm hoping someone will enlighten me ^-^
For now we can learn more about the letter, called 'Ångström' by its closest friends. If you take your time I think you might even fall in love with this lovely character for the humor and wit it brings to our ordinary lives. Thanks, Ångström, thanks for everything! U+00C5 FTW!
If you are interested in further reading I suggest the Danish and Norwegian alphabet article.
