Convert T42 to SFD

The T42 file extension stands for Type 42 and is primarily used for PostScript fonts, which are TrueType fonts encapsulated in a PostScript wrapper. This format was developed by Adobe Systems to enable the use of TrueType fonts in PostScript environments, facilitating compatibility and high-quality font rendering in printing and digital media. Type 42 fonts are widely utilized in desktop publishing and graphic design due to their scalability and precision.

The SFD (Spline Font Database) file extension is primarily used by FontForge, a font editing software. SFD files are ASCII-based, making them human-readable and easily transferable across the internet. They store comprehensive font data, including outlines, character data, and bitmap fonts. Introduced by FontForge, SFD files have evolved to support multiple layers and complex font features. This format facilitates detailed font design and editing, ensuring compatibility across various operating systems.
