svg2ttf: yMax and usWinAscent calculation error
This will cause the line height in Windows to be too large. https://github.com/thx/iconfont-plus/issues/1953#issuecomment-834044570
I guess it is a problem introduced by(v2.1.0) https://github.com/fontello/svg2ttf/issues/25 , and there is a problem with the conversion of the cubic2quad module.
In the result returned by cubic2quad, 32147.26312251112 is abnormal.
[ 'Q', 566.970047, 32147.26312251112, 567.27723, 693.5669409999996 ]
