[XeTeX] XeTeX, "Options for all fonts", and the decimal comma

[Philip TAYLOR]

Does XeTeX not consistently support the use of the decimal comma ?
Empirically I have found that :

> \font \currentfont = "Old English Text MT/I:color=cf0000;embolden=1,5;slant=0,2"
> \currentfont Text

does not give the same results as

> \font \currentfont = "Old English Text MT/I:color=cf0000;embolden=1.5;slant=0.2"
> \currentfont Text
