One of font package (i.e. Adobe Garamond Pro) is not compatible with vowels encoding using xpinyin package. Can I exclude these fonts?

documentclass[margin=10pt]{standalone}

usepackage{xeCJK,xpinyin}

setmainfont{Adobe Garamond Pro} %%problematic with pinyin

begin{document}

  xpinyin*{学而不思则罔}

end{document}

Adobe Garamond does not encode ǎ (U+01CE LATIN SMALL LETTER A WITH CARON) and is also missing ̌ (U+030C COMBINING CARON). I can think of two solutions:

1. 
   

   Use a different font. There are plenty of nice Garamond-derived typefaces out there which do not have such spotty encoding (and are non-commercial!).

   
   
   

   documentclass[margin=10pt]{standalone}
   
   usepackage{xeCJK,xpinyin}
   
   setmainfont{EB Garamond}
   
   begin{document}
   
     xpinyin*{学而不思则罔}
   
   end{document}
   
   

   
   
   

   

   
   
   

   documentclass[margin=10pt]{standalone}
   
   usepackage{xeCJK,xpinyin}
   
   setmainfont{Cormorant Garamond}
   
   begin{document}
   
     xpinyin*{学而不思则罔}
   
   end{document}
   
   

   
   
   

   

   
   


2. 
   

   Remap ǎ (U+01CE LATIN SMALL LETTER A WITH CARON) to something else. Here I map it to just the regular a (U+0061 LATIN SMALL LETTER A). The mapping below is derived from the standard tex-text mapping.

   
   
   

   acaron.map

   
   
   

   LHSName "acaron"
   
   RHSName "a"
   
   pass(Unicode)
   
   ; replace acaron with a
   
   U+01CE > U+0061 ;
   
   ; ligatures from Knuth's original CMR fonts
   
   U+002D U+002D           <>  U+2013  ; -- -> en dash
   
   U+002D U+002D U+002D    <>  U+2014  ; --- -> em dash
   
   
   
   U+0027          <>  U+2019  ; ' -> right single quote
   
   U+0027 U+0027   <>  U+201D  ; '' -> right double quote
   
   U+0022           >  U+201D  ; " -> right double quote
   
   
   
   U+0060          <>  U+2018  ; ` -> left single quote
   
   U+0060 U+0060   <>  U+201C  ; `` -> left double quote
   
   
   
   U+0021 U+0060   <>  U+00A1  ; !` -> inverted exclam
   
   U+003F U+0060   <>  U+00BF  ; ?` -> inverted question
   
   

   
   
   

   The I compile the mapping using the TECkit tool.

   
   
   

   teckit_compile -u acaron.map -o acaron.tec
   
   

   
   
   

   Afterwards it can be used in XeLaTeX.

   
   
   

   documentclass[margin=10pt]{standalone}
   
   usepackage{xeCJK,xpinyin}
   
   setmainfont[Mapping=acaron]{Adobe Garamond Pro}
   
   begin{document}
   
     xpinyin*{学而不思则罔}
   
   end{document}
   
   

   
   
   

   

   
   
   

   You could also choose the mapping U+01CE > U+02C7 U+0061 ;, i.e. caron followed by a, which then renders as

   
   
   

   

   
   
   

   That's not pretty but at least preserves the meaning.

   
   

According to Adobe’s website, Garamond Pro might not have the precomposed character, but it does have the combining caron accent, U+030C.

So, while you might not be able to type ǎ (U+01CE), you should be able to display the same grapheme as (U+61 U+030C).
