There’s a recent proposal of jamming a special unicode character, narrow no-break space, between every character in specific words in an attempt to make them stand out to sighted users without breaking screenreaders.
This sentence contains an e x a m p l e. It reads as the word “example” on Siri, but there are plenty of other screenreaders and environments in use where it does read as separate letters.
It also messes with a lot of other text processing, such as text search and word selection. It’s breaks the fundamental promise of Gemini as a semantic format.
