From the developer:
TTFEdit is an open source GPL editor for TrueType fonts. TrueType is a standard used by modern operating systems like Mac OS X, Windows XP and Linux. There are two different TrueType specifications: from Apple (original author of this technology) and from Microsoft. Mac OS X and Windows XP use own font rendering engines, there is also FreeType library used by Linux. On these three systems the same font will generally look different.
