A designedly small tool used to view graphs of font files, such as .otf OpenType, .ttf TrueType files and .woff2 and .woff web fonts. It helps people finding valid characters in a font file, search special characters existing in a font file or not, compare characters shapes side by side for multiple different fonts, export all valid characters in a font file, generate all valid character shapes of a font file in a PDF file, compare two font file character by character, find out missing characters in a font file, subset a big font file to a new version with smaller size or append missing characters to a font file, etc. The app developed as a small practical font tool that can help people efficiently dealing with different type of fonts in a comfortable way.
