ReproducibleScript:
text .here -height 2 -width $width  -font -misc-fixed-medium-r-normal--20-200-75-75-c-100-iso10646-1
.here insert end \u5b7
pack .here
vwait foo

ObservedBehavior:
The display shows \u05b7 instead of the Hebrew patakh letter.  This font
clearly includes that glyph, as shown by xfd.

DesiredBehavior:
I expect to see a Hebrew patakh letter.

Comment:
same behavior here - I tried arabic 0x06yy & 0xFEyy
I am using xfree 4.0.1 & tcl/tk 8.3.1-
I use the following lines:

    pack [text .t -font "-gnu-unifont-medium-r-normal--16-160-75-75-c-80-iso10646-1"]
    .t insert end $res
# where $res has some unicode text
# I confirmed with ucm (a unicode font display), that the choosen font actually has the desired characters defined.

until now, I could not find any hint, if this for some reason is desired, or a bug.

Thanks for the help

Comment:
The real bug here is that Tk cannot use iso10646 fonts.
For some reason it is basically ignoring that font directive, perhaps because
the FontInfo structure containts unexpected values.  These are all just
clues from informal conversations with Scott S.  Someone needs to dig in
to the font code and figure this one out.  It really damages Tk's I18N capability.
