Hi,

OT = 12 = 12pt

See comments in fontswitch.tex

- fontswitch.tex: minimal example
- tps_arial.tex, tps_timesnewroman.tex, tps_verdana.tex: typescripts
- fontswitch.log for BFT14 + HFV14 -> font error ( same with BFA14 + HFV14 )
- fontswitch.pdf for BFT14 + HFV14 : chapter head is blank ( same with BFA14
+ HFV14 )

After testing different font(switching) combinations...

- BFA14 or BFT14 + HFVx with x not 14pt compile and print the generated pdf
fine
- BFV14 + HFV14 compiles and prints the generated pdf fine
- BFA12, BFT12, BFV12 + HFV14 or HFV12 compile and print the generated pdf
fine

Qué passa ?

you use undefined typefaces; in mkii we default to an empty fontclass which in turn will trigger default fallbacks (i.e. the main bodyfont has no fontclass) while in mkiv we default to the 'modern' fontclass; i'm still not sure if it will be kept this way but if so, i'll make a fallback again (this time to a default fontclass)

At first I didn't understand a thing about your answer, however after digging a bit further and finding out that when replacing 14pt with 14.4 pt ( re: \showbodyfontenvironment table ) it works again. Guess I now understand what "fallbacks"means. :O)

For future reference...
