[XeTeX] Bug or design flaw in Polyglossia 2012/04/29 v1.2.1

[Peter Dyballa]

Hello!

With original XeTeX 0.9998 and recent (development) version 0.9999.2 in TeX Live 2012 I get this PDF output from a Malayalam text:

The empty boxes represent:

Missing character: There is no . in font Rachana/ OT:script=mlym;language=DFLT;mapping=tex-text;! Missing character: There is no . in font Rachana/ OT:script=mlym;language=DFLT;mapping=tex-text;! Missing character: There is no 2 in font Rachana/ OT:script=mlym;language=DFLT;mapping=tex-text;! Missing character: There is no 0 in font Rachana/ OT:script=mlym;language=DFLT;mapping=tex-text;! Missing character: There is no 1 in font Rachana/ OT:script=mlym;language=DFLT;mapping=tex-text;! Missing character: There is no 3 in font Rachana/ OT:script=mlym;language=DFLT;mapping=tex-text;! Missing character: There is no 3 in font Rachana/ OT:script=mlym;language=DFLT;mapping=tex-text;! Missing character: There is no 0 in font Rachana/ OT:script=mlym;language=DFLT;mapping=tex-text;! When the missing characters are obviously Latin, why aren't they taken from a Latin script, from \englishfont for example?
