STIX feedback

• In STIX-Math, some glyphs used as components for stretchy operators should be moved to the Miscellaneous Technical unicode block. This includes those from uni2320.s1 to uni23B3.s1 and from uni23B7.s1 to uni23B9.s1

• There are a couple of delimiters that could be made infinitely stretchy (but they have only fixed size data): U+203E could be able to stretch infinitely (using itself as the extender) U+222B could be made infinitely stretchy (top: U+2320, rep: U+23AE, bot: U+2321) U+27E6 and U+27E7 could be infinitely stretchy using box drawing characters (U+2553, U+2551, U+2559, etc.)

• Other stretchy operators could be added, see the DELIMITERS list in https://github.com/fred-wang/MathJax-dev/blob/open-type-fonts/fonts/OpenTypeMath/STIX-Web/config.py

• STIX-Word is missing glyphs from STIX-General?

• Are most of the glyphs from STIX-Main and STIX-Math duplicate? If so, is it ok not to repeat them in the Web fonts splitting? Can the STIX committee merge the two files?

• Do we have duplicate glyphs for style vs mathvariant (for example alphabets from STIX-Bold.otf and the corresponding characters from the Mathematical Alpha Num block of STIX-Regular.otf)? If so, is it ok not to repeat them in the Web fonts splitting?
