When decoded, it appears to read:
"test message"
The gibberish you see is a series of zero-width or unprintable Unicode characters
I recall lots of unicode obfuscators were popular turning letters to similar looking symbols to bypass filters/censors when the forum/websites didn't filter unicode and filters were simple.
Including RTL-LTR flips, character substitutions etc? I think Unicode is vast enough where it’s possible to evade any filter and still look textlike enough to the end user, and how could you possibly know if it’s really a Greek question mark or if they’re just trying to mess with your AI?
Also makes the output tedious to copy-paste, eg into an editor. Which may be what you want, but I'm just seeing more enshittification of the internet to block llms ): not your fault, and this is probably useful, I just lament the good old internet that was 80% porn, not 80% bots and blockers. Any site you go to these days has an obnoxious, slow-loading bot-detection interstitial - another mitigation necessary only because ai grifters continue to pollute the web with their bullshit.
Can this bubble please just pop already? I miss the internet.
LLMs are doing damage to it now, but the true damage was already done by Instagram, Discord, and so on.
Creating open forums and public squares for discussion and healthy communities is fun and good for the internet, but it's not profitable.
Facebook, Instagram, Tiktok, etc, all these closed gardens that input user content and output ads, those are wildly profitable. Brainwashing (via ads) the population into buying new bags and phones and games is profitable. Creating communities is not.
Ads and modern social media killed the old internet.
Tried with Gemini 2.5 flash, query:

I made a free tool that stuns LLMs with invisible Unicode characters.
*Use cases:* Anti-plagiarism, text obfuscation against LLM scrapers, or just for fun!
Even just one word's worth of “gibberified” text is enough to block most LLMs from responding coherently.
> text obfuscation against LLM scrapers
Nice! But we already filter this stuff before pretraining.

Ultimately the AI will just learn those tokens are basically the same thing. You'll just be reducing the learning rate by some (probably tiny) amount.

Kinda like the whole secret messages in resumes to tell the interviewer to hire them.
Probably going to give screen readers a hard time.
This looks great. Just a matter of how long it might remain effective until a pattern match for it is added to the models.
Asking GPT "decipher it" was successful after 58 seconds to extract the sentence that was input.

The "internet" died long ago.

Usenet, BB forums and IRC already had bot spam before 2005 ended. What even is the old internet? 1995?
