Previously known as "Greater Determinaion Speech Bubble Thin".

[2025.04.06] Shortened the font name from "Greater Determination Speech Bubble Thin" to "Greater Determination SB Thin". Due to the character limit allowed in font names in Windows, the names of both the Regular and Thin variants were truncated to "Greater Determination Speech Bu", resulting in both fonts having the same name, and thus a naming conflict (the Regular font overrides the Thin font and vice versa), which prevented you from using these two fonts if you installed them together.
Unfortunately, I discovered this problem today and have just fixed it. If you have installed both fonts, please uninstall, re-download and reinstall them. Please let me know in the comments if you have a similar problem on MacOS or Linux distributions and if this fixes it. Sorry for the inconvenience. -CT

[2025.04.04] Added missing Greek characters.

The main font for enemy dialogue used in Undertale and Deltarune, created by Toby Fox.

The font looks similar to "DotumChe" at 10pt. The only difference is the character spacing. "DotumChe" has a spacing of two pixels, while there is only one pixel spacing in-game.

i take the undertale/deltarune font and add glyphs that are not from basic latin because everyone always forgets to add them

In the private use area F000-F022 are some chars to help with custom symbols

Font Size: 64 Pixels
Line Spacing: 1 (admittedly kind of a guess)

The font used used literally only once in Undertale, whenever Flowey says "Die." in his battle at the start.

Font Size: 15 Pixels
Line Spacing: 5

The font used in almost all the battle Text Bubbles in Undertale.

Inspired by the Undertale Character that never was, I present to you Semi UT.
Grandpa Semi was originally planned to be a font skeleton and a relative of Sans and Papyrus. In the newest update to Undertale, if you perform a specific action in a fight with Temmie, you'll get to hear his originally planned theme and a little joke that may allude to his actual personality. This theme eventually became Metal Crusher, one of Mettaton's themes.

Please, feel free to use and distribute this font however you like!

Thanks!
