You must go to
https://www.google.com/get/noto/ ...then download and install the following font files:
NotoSans-Bold.ttf
NotoSans-BoldItalic.ttf
NotoSans-Italic.ttf
NotoSans-Regular.ttf
NotoSansHebrew-Bold.ttf
NotoSansHebrew-Regular.ttf
NotoSansPhoenician-Regular.ttf
NotoSansSyriacEstrangela-Regular.ttf
They are hard to find because an alphabetic order ignores the dash character.
Attached, herewith, are 2 RTF files... "CmdBlue Key-Map Tofu by Font Binding.rtf" and "CmdBlue Key-Map Tofu Binding Removed.rtf".
"by font binding" is the file with switched fonts.
It is for your comparison with an ASCII editor.
"binding removed" is where I edited the RTF file to reverse the font binding.
It is for your loading with an RTF editor.
At the start of the document is a table of consonants and descriptions.
On the far left column is a "y". Its row, at the 5th and 6th column is the tofu.
Further down, at the far left column, is a "t".
At the 4th column of that row there is tofu before the Phoenician character.
Do not save anything unless you save it with another name.
If you look at the "by font binding" file with an ASCII editor you will find that it has switched the font to \f10, which is the Hebrew font. It should be \f0, which is the English font.
The same, with the "binding removed" file in the RTF editor, if you click the tofu it will say that it is "Noto Sans Hebrew". It should be "Noto Sans".
It is because RichEdit does not know how to process the Phoenician font... and it is very bad at what it tries to do. It is showing as tofu because there are no English characters in the "Noto Sans Hebrew" font, and it ignores that it is designated as "Noto Sans". It thinks it knows better.
Of course, Font Binding had been eliminated by the Not Sans family of fonts. This is only happening because the Unicode index for Phoenician has made it choke.
