I have this when trying to open a font generated with G2
*** -[_NSInlineData getBytes:range:]: range {2003265670, 4} exceeds data length 62
Could you send me the font?
The HTML test page will not display the following ranges:
1F78C-D
1F797-9
1F79D-F
Also, the symbol which replaces the “missing glyphs” in the test page drops the leading number and only shows the last four characters of the Unicode values.
I would like to suggest that reports on the new apps be pinned at the top of the Forum.
I just tested the file in Safari and Chrome re: the glyphs not displaying. Safari just ignores them, showing nothing, not even a space. Chrome displays a rectangle.
I get the same error message.
Cannot open some files in FontTableViewer!
