biang

Shaanxi cuisine is dope - biang biang, liang pi, yang rou chuar - tasty.

Then I tried making the biang biang noodles that Ethan C demonstrated on YouTube.

The very first input scheme the article talks about is Pinyin, with which you'd input biang by typing...

If you see a big complicated character in a noodle-y context you pretty much know it's going to be biang.

In case of the biang it might be more akin to throwing out a word, because it's rarely used, but still.

Now many (but not all) characters have been disunified as needed, like the infamous Biang character [1] which received two different code points.

I've been using cinnamon (along with szechuan peppercorn and toasted cumin) to make the garlic chili oil for biang noodles at home.

I know that biang is the name of a particular noodle; I'm not aware of kiang; and I believe that duang is a sound Jackie Chan made once.

The Big Biang Theiry is "nerdface." The audience is lsughing at the characters, not with them.

That "biang" character is not a good example since it's not commonly used and was possibly made up by a noodle shop (it doesn't appear in dictionaries).

So by your definition, are "biang", "kiang" and "duang" valid pinyin, considering those are pronounceable and understandable to millions of people, though they don't appear in your table?

(Wikipedia uses SVGs to show the characters; the font recognizes the ideographic description sequence.) However, once support arrives, it will be as easy as typing "biang", since there's currently no character with that pronunciation.
