check_fontname()

static void check_fontname ( const char *  fontname )

static

check a font name abides by Adobe’s rules

Adobe Technical Note #5088 “Font Naming Issues” §2.2:

For compatibility with the earliest versions of PostScript interpreters and with the file systems in some operating systems, Adobe limits the number of characters in the FontName to 29 characters.

As with any PostScript language name, a valid FontName must not contain spaces, and may only use characters from the standard ASCII character set.

Parameters

fontname

Font name to check
