Beyond A–Z
Presets mirror common ASCII sets; the custom alphabet is where you simulate wheels, multilingual tiles, or coding tokens. Combining this with the Random Number Generator handles mixed IDs; the Random Word Generator steps up when entire words—not individual glyphs—matter.
Unique batches
Turning off duplicates enforces sampling without replacement. If you ask for twelve unique letters while only exposing ten glyphs, the generator blocks and explains—you never silently repeat.
