If it looks weird and boxy, you need a Unicode font:

Use it like this:

// Get the Lunicode object, initializing the effects
var luni = new Lunicode();

// Or if you installed lunicode via npm:
var luni = require("Lunicode");

// Encode text. Use one of the effects shown below. Here it's "flip"
var encodedText = luni.tools.flip.encode("Hello World");  // plɹoM ollǝH

// Decode text back to plain ASCII (or reverse encoding)
var plainText = luni.tools.mirror.decode("ƚxɘT ɿoɿɿiM");  // Mirror Text

// Creepify has a few options. Set them before encoding:
luni.tools.creepify.options.top = true; 	// add diacritics on top. Default: true 
luni.tools.creepify.options.middle = true;	// add diacritics in the middle. Default: true 
luni.tools.creepify.options.bottom = true;	// add diacritics on the bottom. Default: true
luni.tools.creepify.options.maxHeight = 15; // How many diacritic marks shall we put on top/bottom? Default: 15
luni.tools.creepify.options.randomization = 100; // 0-100%. maxHeight 100 and randomization 20%: the height goes from 80 to 100. randomization 70%: height goes from 30 to 100. Default: 100

// To convert Unicode text to HTML, use luni.getHTML(text);
// Also converts \n to <br>\n and multiple spaces to &nbsp; &nbsp; &nbsp; ...
var html = luni.getHTML("ǝpoɔıu∩̤"); // &#x1dd;&#x70;&#x6f;&#x254;&#x131;&#x75;&#x2229;&#x324;
