Hi all, I'm having some trouble with bodyfont switching. It involves two fonts that I adapted myself, so it's difficult to make a minimal example. Both fonts are defined in typescripts (these are just examples, it works the same for every typescript I tried). First one is Adobe Caslon: \usetypescriptfile[type-buy] \starttypescript [serif] [caslon] [texnansi] \definefontsynonym [Caslon-Roman] [texnansi-KERN-LIGA- DLIG-ONUM-ACaslonPro-Regularnoct] [encoding=texnansi] \definefontsynonym [Caslon-Bold] [texnansi-KERN-LIGA- DLIG-ONUM-ACaslonPro-Boldnoct] [encoding=texnansi] \definefontsynonym [Caslon-Italic] [texnansi-KERN-LIGA- DLIG-ONUM-ACaslonPro-Italicnoct] [encoding=texnansi] \definefontsynonym [Caslon-Bold-Italic] [texnansi-KERN-LIGA- DLIG-ONUM-ACaslonPro-BoldItalicnoct] [encoding=texnansi] \definefontsynonym [Caslon-Roman-SmallCaps][texnansi-KERN-SMCP- LNUM-ACaslonPro-Regular] [encoding=texnansi] \definefontsynonym [Caslon-Roman-OSF] [texnansi-KERN-SMCP- LNUM-ACaslonPro-Regular] [encoding=texnansi] \stoptypescript \starttypescript [serif] [caslon] [name] \usetypescript[serif][fallback] \definefontsynonym [Serif] [Caslon-Roman] \definefontsynonym [SerifItalic] [Caslon-Italic] \definefontsynonym [SerifBold] [Caslon-Bold] \definefontsynonym [SerifBoldItalic] [Caslon-Bold-Italic] \definefontsynonym [SerifCaps] [Caslon-Roman-SmallCaps] \definefontsynonym [OldStyle] [Caslon-Roman-OSF] \stoptypescript \starttypescript [Caslon] \definetypeface [MyCaslon] [rm] [serif] [caslon] [default] [encoding=texnansi] \stoptypescript Second one is one of my Greek fonts (doesn't matter which one): \starttypescript [serif] [greekgentium] [agr] \definefontsynonym [Greekgentium-Roman] [genagr-GentiumAlt] [encoding=agr] \definefontsynonym [Greekgentium-Italic][genagr-GentiumAItI] [encoding=agr] \stoptypescript \starttypescript [serif] [greekgentium] [name] \usetypescript[serif][fallback] \definefontsynonym [Serif] [Greekgentium-Roman] \definefontsynonym [SerifItalic] [Greekgentium-Italic] \definefontsynonym [SerifBold] [Serif] \definefontsynonym [SerifBoldItalic] [Serif] \stoptypescript \starttypescript[GreekGentium] \definetypeface [MyGreekGentium] [rm] [serif] [greekgentium] [default] [rscale=\getvariable{Greek}{scale},encoding=agr] \stoptypescript The fonts are used thus: \setupbodyfont[MyCaslon,12pt] \switchtobodyfont[MyGreekGentium] Switching works when I set the bodyfont size to 9,10,11,12pt, but not if it is set to any other value. In that case, I get these messages in the log file Missing character: There is no a in font nullfont! Missing character: There is no > in font nullfont! Missing character: There is no u in font nullfont! Missing character: There is no t in font nullfont! Missing character: There is no o in font nullfont! etc. I must be missing something obvious about typefiles, but can't see what? Any help will be appreciated. All best Thomas
