On TeX.SX there are a lot of questions of the form "How do I typeset [some phonetic symbol]?" For example:
- Typesetting modifier letter U+02ED
- The near-close, near-front unrounded vowel symbol
- The IPA symbol for the labiodental flap (ⱱ)
- How can I get the character ʟ̟ ?
- How can I get the ð symbol with TIPA?
- Is there a symbol for Dark 'l' (ɫ)?
- How do I get an Uvular Trill <ʀ> IPA symbol?
One of the issues that often comes up in answers to these questions is whether International Phonetic Alphabet (IPA) symbols should be typeset using
tipa(a font package that uses T3 encoding for phonetic symbols) with pdfLaTeX,
- a Unicode font with XeLaTeX/LuaLaTeX, or
- a combination of these methods, as discussed at Custom phonetic font with tipa and fontspec.
What should a user consider when deciding which of these approaches to use?
This question is related to Is \aa or å preferred?, but I'm focused on the
tipa package specifically here, not the broader question of LaTeX-based macros vs. Unicode. This is also related to questions about pdfLaTeX vs. XeLaTeX vs. LuaLaTeX, but again I'm focused on
tipa, which can be used with any of those.
