problems with ttf fonts (hebrew), can go back to courier font.

[Uwe Brauer]

Hello

Using GNU Emacs 24.3, I usually use 

(set-face-font 'default "-etl-*-bold-*-*-*-*-180-*-*-*-*-ISO8859-8") for
hebrew. 

However I have also the ttf font Guttman Yad-Brush, which is a
handwritten based hebrew font, without really ASCII support.

So when I use 
(set-face-font 'default "Guttman Yad-Brush")

then this font is activated, Hebrew chars are displayed correctly but
all other ASCII symbols save numbers are not (I see empty boxes instead)

*However* when I want my standard courier font back via
(set-face-font 'default "-*-courier-bold-r-*-*-18-180-*-*-*-*-*-*")

Then this does not work, the empty boxes remain.

Is this a bug?
