This font has precomposed "Latin small letter a with macron and acute"
( \char"0F01 resp. \XeTeXglyph3066 ).
The makers of this font have placed their a-macron-acute at a codepoint
assigned to another character in Unicode; very, very bad practice. One can
always create a character that does not exist in Unicode in the Private Use
Area, if absolutely necessary, but it's better to use existing characters if
possible. If one uses the precomposed a-macron followed by a combining
acute (or 'a' plus combining macron and combining acute), the meaning of the
text will always be clear even if the display is not perfect. Using a PUA
value (or a wrongly encoded font such as TLL) will result in nonsense if the
person viewing the document does not have the customized font on his/her
system.
