I have been messing around with creating a homoglyph keyboard for Android, but I’m wondering if it’s even worthwhile. Is there any benefit to masking your messages with homoglyphs? Primarily I think it could defend against an LLMs ability to easily scrape messages. In my experiments ChatGPT and DeepSeek both get confused by homoglyph messages unless you instruct it to determine the likely alphabet characters and numbers for each individual character.

Most of the characters you have there are still regular letters, too, just with accents and fullwidth variants, so it’s pretty easy to map these to simpler character sets like ASCII. You’d probably have to get real creative with abusing multiple writing systems like cyrillic, katakana, and so on.
