Alt-F7 "Find Text" does not find text in files

[mplaut]

That are Code page 1255 any more. I have a lot of those. Is there any way to force it to find text properly there?

I guess Windows Code page must be set to the correct number.

If your system is defined as windows 1255, you just have to chose the ansi option.
Another way is to enable hex and from an editor able to switch from 1255 to hex past your search string from hex number.
You can also use the translit wdx but you will have to define a dedicated translit file from 1255 to UFT8.
