EnglishWhat Utilities Are Available on Beej's Web Page?
Updated
Beej's Web Page (beej.us) lists three utilities in its "Utilities" section: a Unicode Pixel Art Tool, a Rot13 encryption tool, and Gunfight Unlock. The first two are general-purpose web tools, while Gunfight Unlock is a narrowly targeted helper for an old PalmOS game. All three are presented as things you can use directly from the site rather than as downloads or installable software.
The Three Utilities at a Glance
| Utility | What it does | Who it's for |
|---|---|---|
| Unicode Pixel Art Tool | Builds pixel art using Unicode characters | Anyone making text-based or character-grid art |
| Rot13 encryption | Applies the ROT13 substitution cipher to text | People who need a quick, reversible text obfuscation |
| Gunfight Unlock | Unlock helper for the ancient PalmOS game Gunfight | Players of that specific legacy PalmOS game |
Unicode Pixel Art Tool
This tool is for creating pixel art where each "pixel" is a Unicode character rather than a colored square. That makes it useful when you want an image to survive as plain text — in a terminal, a text file, a forum post, or any context where you can't attach a real image but can paste characters.
The practical workflow is: choose your characters, lay them out on a grid, and copy the resulting text. Because the output is just text, it stays editable and portable. If you've ever seen ASCII art and wanted something with a wider palette of glyphs, this is the same idea with Unicode's larger character set.
Rot13 Encryption
ROT13 ("rotate by 13") shifts each letter of the alphabet 13 places, so A becomes N, B becomes O, and so on. Applying it twice returns the original text, which makes it self-inverse — no key and no separate decryption step.
It is not real security. ROT13 is a way to hide text from casual reading, not from anyone who actually wants to read it. Typical uses are spoilers, puzzle answers, punchlines, or offensive content you want readers to opt into. If you need actual confidentiality, ROT13 is the wrong tool.
Gunfight Unlock
This one is the odd entry out: it exists to unlock the ancient PalmOS game Gunfight. It's a compatibility fix for a piece of software from the PalmOS era, not a general utility. If you're not running that specific old game, this tool has no use for you. If you are, it's the reason the entry is on the page at all.
How These Fit the Rest of the Site
The Utilities section sits alongside Beej's better-known material — the programming guides and tech blog under "Stuff to Learn," and the public-domain book digitization project under "Books." The utilities are small, single-purpose tools rather than a software suite, so treat each one as a standalone page you visit when you have that specific task. There's no indication on the page of pricing or login requirements, so check each tool's own page before assuming how access works.
