Hello all, I'd to explain some effects in the .pdf from the code bellow. It was copied from co-font.pdf, pg. 19-20; just "Abc" was added to try something. --- \enableregime[cp1250] \starttext $Abc\sqrt{625}=5\alpha$ $\bf Abc\sqrt{625}=5\alpha$ $Abc\sqrt{625}=\bf5\alpha$ $\bfmath Abc\sqrt{625}=5\alpha$ \definetypeface[whow][mm][math,boldmath][modern][default]%[encoding=texnansi] [] $Abc\sqrt{625}=5\alpha$ $\bf Abc\sqrt{625}=5\alpha$ $Abc\sqrt{625}=\bf5\alpha$ $\bfmath Abc\sqrt{625}=5\alpha$ \usetypescriptfile[typeface] $Abc\sqrt{625}=5\alpha$ $\bf Abc\sqrt{625}=5\alpha$ $Abc\sqrt{625}=\bf5\alpha$ $\bfmath Abc\sqrt{625}=5\alpha$ \stoptext --- Things I cannot do or understand: - The "alpha" symbol is not printed as soon as it's used in \bf or \bfmath mode (lines 2-4 in each paragraph). Why? How to make it appear? - - The same effect may be observed in the co-fonts.pdf at the pg. 19 at the lowest line - there is bold font working, but "alpha" is missing as well. - - - Unfortunately, there is no fully working example in the document with bold math and "alpha" together. - In my example, normal (thin) "Abc" is shown a bit slanted (as should be in math mode). Once it is used in bold math mode, it's no more slanted but "vertical" as normal text. Is there a way how to keep the "slantedness" even in math bold mode? (This is e.g. often used to mark vectors.)
