EBFONT

Font file format validation

On Solaris, EBFONT is errno value 57. The base message is bad font file fmt, but the useful diagnostic context is narrower than the short message: solaris rejected a font file or console-font format.

Use the Solaris-specific errno table first, then compare with POSIX only for portable behavior. Some Solaris values share names with other UNIX systems but have different numbers or more specific historical meanings.

What to check

Check the specific console or display utility that loaded the font.
Confirm that the file format matches the expected legacy font format.
Do not diagnose it as character-encoding failure; EILSEQ is the byte-sequence error.
