I went to a museum in Morocco that was specifically showing Arabic calligraphy in the shape of trees or people or other common objects and was absolutely blown away.
Indelibly printed on my mind.
I saw saw Arabic calligraphy and I was like oh s*** they got the written word correct.
I don't think there's any words that "look handsome" though what I was a kid, the first time I read the word "gobbledygook" I could not stop laughing for at least 5 minutes. Then I had to go look it up in a dictionary (because that was the style at the time).
One of my kids is named Ivy and she was the first to learn how to write it because it's one stick, two sticks, three sticks. Her under 2 year old sister was at the library once and pointed to a book and said "Ivy" and yep, that was on the spine of the book. So I love that word because it made two of my kids understand written language.
Chinese and Japanese would have so many. My favorite is probably 緑 which means green. I also like the simplified Chinese horse: 马. Special shoutout to 凸 meaning convex, 凹 meaning concave, and 凸凹 meaning bumpy (not sure if this is true in Chinese). There's thousands to choose from so of course there are a lot of other handsome one-character words, but those are the first few I thought of.
