Dear Hans,
thank you, that solution worked well! May I suggest to add something like
dimensions = {
default = {
[0xFE932] = { width = 150 }, -- prime
[0xFE933] = { width = 435 }, -- double prime
[0xFE934] = { width = 720 }, -- triple prime
[0xFE957] = { width = 1005 }, -- quadruple prime
},
},
(or the values 200, 500, 800, 1100 if you prefer) to the font goodie
file for lucida in the distribution?
Again, thanks for your time, it is very much appreciated.
/Mikael
