24 alternatives to Unicode Steganography
I built a demo of two Unicode steganography techniques, zero-width characters and homoglyph substitution, in the context of AI misalignment. The first is about the use of two invisible zero-width characters (ZWS and ZWNJ) to binary encode text. The second is much cooler. Most characters in the Latin and Cyrillic alphabets look nearly identical, but have different unicode. If you have text to encode and convert it into binary representation (1s and 0s), you could take plain english "carrier" text and for each 1 in the binary representation you could substitute the Cyrillic letter equivalent.…
Unicode Steganography is a demo tool that implements two techniques for hiding text within other text. The first method uses invisible zero-width characters to binary encode messages. The second uses homoglyph… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

I’m building a Unicode reference where each symbol has its own dev-friendly page with all relevant encodings. Example: [https://fontgenerator.design/symbol/almost-equal-to](https://fontgenerator.design/symbol/almost-equal-to) Includes Unicode, HTML, CSS, JS, UTF-8/16 bytes, URL encoding, and usage examples. The same structure is used across thousands of symbols (math, arrows, currency, tech/UI, punctuation). Built because existing references are fragmented. Feedback welcome.

Hello, everyone. I built Unicorn: an embeddable MISRA C:2012 implementation of essential Unicode Algorithms. Unicorn is designed to be fully customizable: you can select which Unicode algorithms and character properties are included or excluded from compilation. You can also exclude Unicode character blocks wholesale for scripts your application does not support. It's perfect for resource constrained devices like microcontrollers and IoT devices. About me: I quit my Big Corp job a few years back to pursue my passion for software development and this is one of my first commercial releases.

Good morning HN! For a while now I have been toying with this idea and now finally have a working prototype. This project allows you to encode secret messages into ordinary looking text by using arithmetic coding with a probability model derived from an LLM. By encrypting the message and then decompressing the encrypted message using the arithmetic coder, you get output which looks just like randomly sampled output from the LLM. Except, it actually encodes your secret messages in the specific choices of tokens. By using authenticated encryption, only a user who knows the key can know that a…

Hi HN, Unicode “cursive” and script-style fonts are widely used on social platforms, but many of them silently break depending on where they’re pasted — some render as tofu, some get filtered, and others display inconsistently across platforms. I built a small web tool that explores this problem from a compatibility-first angle: Instead of just converting text into cursive Unicode characters, the tool: • Generates multiple cursive / script variants based on Unicode blocks • Evaluates how safe each variant is across major platforms (Instagram, TikTok, Discord, etc.) • Explains why…
