Gaster Translator
Decode W.D. Gaster’s mysterious Wingdings dialogue from Undertale with our free Gaster translator. Paste any Wingdings symbols below — including the hidden “Entry 17” — and read what the fallen royal scientist was trying to say.
Who Is W.D. Gaster?
W.D. Gaster is the former royal scientist of the Underground in Undertale, the indie RPG by Toby Fox. According to the game’s lore, Gaster fell into his own creation — the CORE — and was shattered across time and space. He never appears directly in normal gameplay, but his presence lingers in hidden rooms, unused dialogue files, and one of the game’s most famous secrets.
Everything Gaster “says” is written in Wingdings, the Microsoft symbol font. His name itself is a clue: W.D. stands for WingDings.
Where Wingdings Appears in Undertale
Entry 17
The most famous Gaster text is Entry 17, found in the game’s data with a 1-in-101 chance of appearing in a hidden room. When decoded from Wingdings, it reads as a dark, fragmented lab log about an experiment gone wrong. Paste it into the translator above to read it yourself.
The Gaster Followers
Three grey, faceless NPCs — the Gaster Followers — speak about the fallen scientist in Wingdings. Each one reveals a fragment of what happened to him.
Mystery Man Sprite
A hidden sprite nicknamed the “Mystery Man” is widely believed to be Gaster himself, standing silently behind a grey door.

Why Gaster Speaks in Wingdings
Using Wingdings was a brilliant storytelling choice: the symbols look like language while remaining unreadable, which makes Gaster feel truly “shattered across time and space” — present, but impossible to understand without effort. Decoding his text is a rite of passage for Undertale fans, and it is exactly what this page is built for.
