About the Blue Values: Please read the Handbook chapter about hinting, and the blueScale and blueShift entries in the Appendix.

About the BBox: Please read the Vertical Metrics tutorial: https://www.glyphsapp.com/tutorials/vertical-metrics

About the glyph names: Are you using custom naming? If you do, you will have to know what you are doing. If you disable it in File > Font Info > Other Settings, Glyphs will take care of the renaming.

About ‘Single Face Test 23: Warn if any accented glyphs have a width different than the base glyph’: If these occurrences really are unintentional, please read about automatic alignment in the handbook.

Thank you. I will study. BTW glyph names is OFF

The check are mostly meant for the standards of the internal Adobe font production. So not all of them are more recommendations then errors.

The names are fine and where in use by adobe but in some point they desiccated to use the uni-names instead. So the names are fine.

Thanks6 Georg. I think the same. Because I’ve tested Open Sans also and there was same errors and warnings excerpt warning related to BBox: “The font bounding box in the hhea table ‘(-1346, -434, 2271, 1877)’ differs from that in the CFF table ‘[-340, -434, 2271, 1877]’. Artnoova-Regular.”

Btw, how much important this warnings? I tested my font with different soft on mac, windows and everything looks good. No errors was noticed

Read the warnings and see if they point you to something unintentional. Otherwise, do your own testing. Test in real apps, like in Adobe apps and Word on Windows. If it works, it works
