Font licenses for test font files

[bkmgit]

SparseFont, noto_handwriting and test_glyphs do not have any license information. Is it possible to add this or create font files which test the appropriate features but have licenses?

As previously noted in https://github.com/harfbuzz/uharfbuzz/pull/226#issuecomment-2566561643, I see that:

• tests/data/SparseFont.ttf was introduced in https://github.com/harfbuzz/uharfbuzz/pull/84, without obvious provenance
• tests/data/noto_handwriting-cff2_colr_1.otf and tests/data/test_glyphs-glyf_colr_1.ttf were introduced in https://github.com/harfbuzz/uharfbuzz/commit/5a80c3eaeea58d36b15a76dba45639294e0200ce, taken from Harfbuzz where they were introduced in https://github.com/harfbuzz/harfbuzz/commit/30a6fd04d00624129b13b20fb755d6c1c4982637, but their ultimate provenance is unclear (to me)

• tests/data/noto_handwriting-cff2_colr_1.otf and tests/data/test_glyphs-glyf_colr_1.ttf were introduced in 5a80c3e, taken from Harfbuzz where they were introduced in harfbuzz/harfbuzz@30a6fd0, but their ultimate provenance is unclear (to me)

Those are from here:

Thanks! So it looks like those would be Apache-2.0, https://github.com/googlefonts/color-fonts/blob/main/LICENSE. They’re built by https://github.com/googlefonts/color-fonts/blob/main/build.py according to configurations https://github.com/googlefonts/color-fonts/blob/main/config/noto-cff_colr_1.toml and https://github.com/googlefonts/color-fonts/blob/main/config/noto-glyf_colr_1.toml, respectively, based on SVG sources in https://github.com/googlefonts/noto-emoji/tree/b960563a023fbd1337227bf2a8a2d5a91889a333, which also carries an Apache-2.0 license https://github.com/googlefonts/noto-emoji/blob/b960563a023fbd1337227bf2a8a2d5a91889a333/LICENSE. Some are from https://github.com/googlefonts/noto-emoji/tree/b960563a023fbd1337227bf2a8a2d5a91889a333/third_party/region-flags, which has https://github.com/googlefonts/noto-emoji/blob/b960563a023fbd1337227bf2a8a2d5a91889a333/third_party/region-flags/LICENSE – so technically the flags may be under some kind of public domain dedication rather than Apache-2.0, if one wants to be extremely precise.
