International Phonetic Alphabet (IPA) fonts
The following is a comprehensive list of modern open-source fonts that support IPA symbols.
Designed by: ,
The fonts with the best IPA coverage include Charis, Gentium Plus, Doulus, and Andika, which were all designed specifically for linguists by SIL International. Google's Noto Sans and Noto Serif also have great coverage, as these fonts were designed with the goal of covering as many Unicode symbols as they can in a neat, modern style (no font in existence covers all 136,690 Unicode characters).
The other fonts on this list will cover all the IPA symbols and diacritics, however some have a few limitations to be aware of: some render some of the less common diacritics in slightly skewed positions; some may not render combining tone contours; and some do not support ⱱ (which was a later addition to the IPA).
Various Microsoft fonts also support IPA symbols extensively. These include Arial, Calibri, Cambria, Consolas (monospaced), Courier New (monospaced), Lucida Sans Unicode, Segoe UI, Tahoma and Times New Roman.
