Upstream SHA-256: a3041811a78c361b1de50f953c805e0244951c21c5bd412f7232ef0d899af0da

The font was instantiated at weight 400 with fontTools 4.68.0 and renamed
JUMP CJK. BASE, GDEF, GPOS, GSUB, STAT and DSIG tables were removed.
The original license accompanies the font in OFL-NotoSansSC.txt.

For the PDF version, tools/distinguish-pdf-glyph-aliases.py assigns distinct
glyph IDs to Unicode aliases. The aliases share the original outlines
and advance widths. This preserves separate entries in PDF ToUnicode maps.
