If you wanted something that worked like \showhyphens you could do this

It produces the following with xetex



Underfull \hbox (badness 10000) in paragraph at lines 1--1
[] \tenrm good-bye hy-phen-ation

Underfull \hbox (badness 10000) in paragraph at lines 8--8
[] \tenrm goodbye hyphenation

Underfull \hbox (badness 10000) in paragraph at lines 55--55
[] \tenrm good-bye hy-phen-ation
 )


where the first is with its default cm font, second is just changing it to
use Times Roman, then third is redefinition of \showhyphens


\showhyphens{goodbye hyphenation}

\font\tenrm = "Times New Roman" at 10pt
\hyphenchar\tenrm=`\-
\tenrm


\showhyphens{goodbye hyphenation}

\catcode`\@=11
\def\showhyphenspace#1 {%
\ifx\valign#1\valign\else
#1\vadjust{\penalty\@ne} \expandafter\showhyphenspace
\fi}
