The FCONV.exe from Agfa (1994) is not very useful. There are not many TrueType fonts that it can convert (it can't even convert the BASE 14 fonts that come with Windows).
We have in-house programs that can convert TrueType fonts into PCLETTO (.SFT) or PCLEO (.SFS) scalable formats. However, we do so only as a service for font or logo authors.
We withdrew our AllType, Universal Typeface Converter from the market because most interested parties were just interested in bootlegging fonts from third party authors.
Contact me only if you have a serious, commercial need to legally convert body text, logo, signature or other fonts.
