Title text: I don't see how; the C0 block is right there at the beginning.
Cueball and Megan hired a skywriter to write some text provided in Unicode. Skywriting is using an airplane to write words in the sky with controlled releases of smoke. Unicode is a standard for encoding text which supports an incredible variety of characters and modifiers. An interrobang (‽) is a combination question mark and exclamation mark. A diacritic is any symbol added to a character ( ´ , ˘ , ˇ , ¨ , etc.), usually an accent mark being added to a letter. In Unicode, combining diacritics are represented as separate characters, but are rendered graphically as modifications to the previous one. The request appears to be particularly strange, given that diacritics are supposed to go over letters and not punctuation marks.
Apparently the skywriter got so confused about their instructions that he not only rendered the text incorrectly, but also lost control of the plane. The skywriter's errors and the phrase "Unicode support" play off the common issue of software rendering Unicode symbols incorrectly.
The title text refers to the C0 Block, the name for the first 32 character codes in Unicode (and ASCII), traditionally called control characters. Cueball wonders how the plane could have lost "control" when the "control characters" are easily found.

- Cueball talking into radio: "No, the combining diacritics go over the interrobang!"
- Megan, with radio lowered: "Oh jeez, I think he's lost control."
- The skywriter we hired has terrible Unicode support.
