This is the fourth installment of the Monthly Topic Challenges with topics suggested and voted on here. This month's topic is "Cross-non-words" (suggested by Stiv) and will span from the 1st of October to the 31st of October. During this period, we will compile the list of relevant questions and post it as an answer to this question.
In the meantime, please go and propose and vote on future challenges!
Everyone have fun, and happy puzzling!

The suggestion is copied to this post for posterity.
The challenge here is to produce a crossword wherein some (or all) squares are filled not with typical English alphabet characters, but with something else altogether.
Such a crossword might contain no English alphabet characters at all (e.g. each square instead contains an image, a special character, a number, etc.) or each answer within it features at least one square containing one such alternative... Crucially, no words in the grid should appear fully spelled out with English alphabet characters.
Note: This is not merely a repeat of FTC #43: Variety Crossword Grids from November 2020 - here it is the content of the squares wherein the variety lies, as opposed to the structure of the grid...
