Hi all, First I admit that I've never understood the typescript part of ConTeXt... I've been using the following recipe for boldmath. The latin letters appears fine in bold italic font, but the greek letters do not appear. --------------------------- \definetypeface [boldmath] [mm] [boldmath] [latin-modern] [modern] [encoding=texnansi] \setupbodyfont[10pt] \starttext $a b c \alpha \beta \phi$ $\bi a b c \alpha \beta \phi$ \stoptext --------------------------- Looking at the log file, I found the following error message: --------------------------- Missing character: There is no α (U+03B1) in font LMMath10-Regular! Missing character: There is no α (U+03B1) in font LMMath10-Regular! Missing character: There is no β (U+03B2) in font LMMath10-Regular! Missing character: There is no β (U+03B2) in font LMMath10-Regular! Missing character: There is no ϕ (U+03D5) in font LMMath10-Regular! --------------------------- Apologize for dumb questions. I wonder why LMMath Regular is looked-up here, I thought we should be looking-up LMMathItalic10-Bold? Thanks a lot. regards, ShenChen
