With assistance from the Association, the Journal of the Acoustical Society of America has updated its requirements for authors so that Unicode-compliant fonts are now specified when IPA symbols are included in a manuscript. Through 2012, the Journal continued to require authors to use SIL IPA93 fonts, even though they are no longer supported by SIL.
The new information for JASA authors can be found here (external link to PDF file; See section V. G. on page 10). A PDF file which lists all IPA symbols with their phonetic definitions and information about their Unicode characters can be found here (external link to PDF file).
The Journal of the IPA also updated its information for authors about phonetic fonts in 2012; see here for information.
