Hello, suppose that i need to merge two pl fonts into one vpl font (e.g. the first font is 7-bit font like cmr10 and the second has only glyphs with codes above 127). e.g., the following line will do the job: \installfont{lhr10}{cmr10,llr10}{LCY}{LCY}{cmr}{m}{n}{<10>} fontinst, when it creates mtx files, converts fp numbers in pl files to integers and looses some digits [typically, at least 3 decimal digits are lost] (yes, the error is small but i want an exact result :). i'm sure that TeX has the ability to preserve all decimal digits used in pl files when generating a vpl file: we should not use integer count registers but dimen registers when dealing with fp numbers (obviously :). So, in this case this is not a TeX limitation, but a fontinst design issue. Would it be possible to use fp numbers in fontinst where possible? Could it be implemented in the next version of fontinst? BTW: some time ago, i heard of other font installation tools (written in perl). could you give me pointers where/if they are available for testing? Best regards, -- Vladimir.
