Who Is W.D. Gaster?
W.D. Gaster is Undertale's ghost in the machine — the previous royal scientist who, according to in-game legend, fell into his own creation and was shattered across time and space. After the accident, the world forgot him: his records were erased, his followers are glitches, and his history was rewritten with Dr. Alphys in his place. Creator Toby Fox never gave him a single scene of normal dialogue — instead Gaster exists in fragments hidden behind unlikely conditions, which is exactly why fans have spent a decade collecting them.
The name is the clue: W.D. stands for Wing Dings. When Gaster communicates, his text is set in the Wingdings font — most famously in a laboratory log written entirely in it. The river person's warning, "beware of the man who speaks in hands", points at the same idea: Wingdings symbols include pointing hands, so a man who speaks in hands is a man who speaks in Wingdings.
This page discusses Gaster as a cultural phenomenon and decodes his lines as text. All symbols shown are standard Unicode characters; no game assets are used.

How to Speak Wingdings Yourself
Speaking "Gaster" is simply encoding English into Wingdings. Type your sentence into the translator at the top of this page and it converts live as you type. Keep the Text style selected so the symbols stay monochrome like the game's rendering, then copy them into Discord, a YouTube description or a fanfic.
Remember the two rules of Wingdings: uppercase and lowercase produce different symbols, and numbers/punctuation are symbols too. A message that mixes cases will decode back exactly as you typed it — this translator preserves everything, including line breaks.

Frequently Asked Questions
▸Does Gaster speak Wingdings?
Yes. In Undertale, the former royal scientist W.D. Gaster's dialogue is rendered in the Wingdings font — his name literally abbreviates "Wing Dings". When his words appear (most famously in Entry Number Seventeen), they are typed in Wingdings, which fans decode with a translator like this one.
▸What does Gaster say in Entry Seventeen?
Entry Number Seventeen is Gaster's chilling lab log: it describes the darkness getting "darker, yet darker", an experiment that went too far, and ends with him asking what readers think happens when you fall into the darkness. Type the words into the translator above to see exactly how they look in Wingdings.
▸Is Gaster Mode different from regular Wingdings?
No. Gaster speaks in standard Wingdings (version 1), so Gaster Mode here is identical to the classic font — the separate button exists because Gaster fans search specifically for a "Gaster translator". For other fonts use Wingdings 2, 3 or Webdings.
▸How do fans use Gaster Wingdings?
Commonly for secret messages in fan fiction, Discord roleplay, Tumblr posts and Deltarune theory videos — hiding a hint "in Gaster's voice" that readers can decode. Convert your text above, copy the symbols, and paste them anywhere; use Text style to keep them black-and-white like the game.
▸Where does Gaster appear in Undertale?
Gaster never appears in normal gameplay. He exists through fragments: the Mystery Man room reachable only by luck in Waterfall, the eerie Entry Seventeen-style log in the True Lab, a follower who holds a piece of his head, and name checks by NPCs like the river person's "Beware of the man who speaks in hands". These brushes with an erased character made him one of gaming's most-discussed mysteries.
