Anyone has comment on the above questions please? And one more: Could we copy glyphs from symbola font and reuse in Wine fonts? Symbola font is "offered free for any use", according to its official page: http://users.teilar.gr/~g1951d/
It also pass fedora's license review: https://bugzilla.redhat.com/show_bug.cgi?id=532819
FWIW, Yida Wang is working on an experiment program, using smart computer vision algorithm like PCANet ( http://arxiv.org/abs/1404.3606 ), to discover similar wingdings glyphs from symbola fonts automatically.
So far the result is not bad, see the two attachments, windings.png is wingdings glyphs, and symbola.png is similar glyphs from symbola which map to wingdings glyphs. The result is not complete, it is just an experiment.
Once the program is trained and optimized we could use it to discover more glyphs for wingdings/wingdings2/wingdings3/webdings/mtextra and even more, which are useful for not only Wine, but also Libreoffice, WPS and other Linux application. That might also bring a new question: would we want to redistribute Wingdings and similar fonts outsite of Wine, so that they could be installed to system directories like /usr/share/fonts/truetype and reused by application like WPS and Libreoffice?
Any comment is still great appreciated!

GPL and Apache licenses are not compatible with LGPL. Whether the distinction is meaningful for fonts is debatable, but I think it's better to follow the same guidelines as the rest of the code.
The Symbola license looks OK, though you'd of course need to give proper credit even if not required.
It's also not clear that copying the glyphs is the right approach, as opposed to for instance setting up font replacements.

Thanks a lot for comment, that helps a lot.

Setting up font replacements seems won't work for Wingdings/Windings2/Winding3/Webdings/MT Extra, for example, I didn't find any font which is possible to replace Wingdings.
Like http://unicode.org/~asmus/web-wing-ding-ext.pdf and http://www.alanwood.net/demos/wingdings.html said, while there are some glyphs in Unicode standard look similar to Wingdings glyphs, but Wingdings itself doesn't follow unicode standard, for example, 0x21 in Wingdings is a pencil, but in Unicode, U+0021 should be the character '!'. The idea here is to use the Unicode Dingbat range character pencil (U+270F) to replace Windings pencil (0x21)
By copying the glyphs and creating an alternative font, we can not only also solve the Wingdings font problem for Wine applications, those alternative fonts could be freely reused by other Linux application like WPS Office Suite and LibreOffice.
