The baseline about which mathematical characters are centered in vertical writing mode. Adobe has converted the entire Adobe Type Library into this format and now offers thousands of OpenType fonts.

The TTF version is also the better choice when you’re using it on Windows because some older versions of the Windows OS (prior to Windows 2000) don’t render Type1 fonts correctly.

OpenType fonts containing PostScript data, such as those in the Adobe Type Library, have an .otf suffix in the font file name, while TrueType-based OpenType fonts have a .ttf file name suffix. © 2020 Uqnic Network Pte Ltd. All rights reserved.
