Ionicons not well aligned vertically

Hi,

could you please ensure that all icons are equally vertically positioned? Each of the icons has different spacing above and below the icon in the font file. Same for left and right. This makes it unusable in environment where you want to make the icon well positioned, e.g. in the mid of a circled button on any screen resolutions.

Thanks!

Start by locating the icon font source and generation process, then compare the vertical and horizontal spacing of several icons in the rendered font. Done means the icon set has consistent positioning inside UI elements such as circled buttons across screen resolutions; the issue names no specific files or tests.
