1. Avoid write lastChange and displayString to version control

2. Check Use Typo Metrics to get more consistent vertical metrics - https://learn.microsoft.com/en-us/typography/opentype/spec/os2#fsselection - https://googlefonts.github.io/gf-guide/metrics.html#5-use_typo_metrics-must-be-enabled

3. Resolve #21 #37 #169 - #21 #37 "Hanging Font": Miss configure typo and hhea value. Adjust this value will "centering" glyphs across the vertical bounding box. - #169 Probably same as above, tweaking typo and hhea does resolve the line-height or leading default to 1.2 or 120% from the upm value.

Note that "Gcommaaccent" may be truncated in environments that have overflow: hidden.
