dynamic font not centered

[beermoney]

creating a button with a dynamic font centered in the middle, the text appears un-centered

repro:
drag NGUI button prefab into scene
change font to dynamic and then to using "oliver's barney" font from the free square pack font pack (https://www.assetstore.unity3d.com/#/content/4235)
change the font size to 50 to exaggerate the displacement

this is using NGUI 3.0.8, (previous versions 3.0.7 f3, worked fine with this font)

Unity doesn't provide any clear way of properly retrieving the baseline for the character, so all ways of doing so manually are, pretty much -- hacks. Can you send me the font itself to support at tasharen.com? I'll have a look.

hope it's ok to attach here

Hey Aren,

I'm seeing this issue again with NGUI 3.5.3 and Bitmap/NGUI  fonts!

[ArenMook]

In case of the font you posted the issue occurs because of the vast difference between how characters "_" and "`" are positioned in the font. Try drawing them. The "`" in particular is way higher than it should be. The creator of the font didn't respect the bounds at all.

P.S. I've modified the freetype parsing logic to calculate the offset a little differently in 3.5.4 though:

1.                         int baseline = size + min;
2.                         baseline += ((max - min - size) >> 1);
3.  
4.                         // Offset all glyphs so that they are not using the baseline
5.                         for (int i = 0; i < entries.size; ++i)
6.                         {
7.                                 BMGlyph glyph = font.GetGlyph(entries[i], true);
8.                                 glyph.offsetY += baseline;
9.                         }
