Just take a look at: http://www.unicode.org/charts/PDF/U0370.pdf The code points are U+03B5 and U+03F5. --roozbeh On Wed, 16 May 2001, Phil Parker wrote: > On 05/15/2001 at 03:04 PM, Lars Hellström <[log in to unmask]> > wrote: > > >I math fonts something like that could be used to handle the choice > >between \epsilon and \varepsilon.
