I don't get it. Gill Sans MT supports Small Caps without any issue in Word and Powerpoint. Font recognition apps event identify it. And yet, there is no way I can get them.
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Gill Sans MT}[
SmallCapsFeatures={Letters=SmallCaps},
SmallCapsFont={*},
]
\begin{document}
\textsc{Small Caps.}
\end{document}
Word processors often have the capability of faking fonts that aren't in the system; with TeX this is not possible, because we're doing fine typography, not just printing whatever.
With several limitations (only text, no commands), you can fake small caps. For your simple application it should do.
Here I use Gillius ADF as I don't have Gill Sans MT.
\documentclass{article}
\usepackage{fontspec}
\setmainfont{Gillius ADF}[% replacement for Gill Sans
NFSSFamily=gilliusadf,
]
\newfontfamily{\scaledgillius}{Gillius ADF}[Scale=0.8,FakeBold=1.5,WordSpace=1.25]
\ExplSyntaxOn

\krebs_fakesc:n { #1 }

\group_end:
}
\cs_new_protected:Nn \__krebs_fakesc:n

\text_map_inline:nn { #1 } { \__krebs_fakesc_letter:n { ##1 } }
}
\cs_new_protected:Nn \__krebs_fakesc_letter:n
{
\int_compare:nTF { \char_value_uccode:n { `#1 } = `#1 }
{
{\fontfamily{gilliusadf}\selectfont #1 }
}
{
\char_uppercase:N #1
}
}
\ExplSyntaxOff
\begin{document}
\fakesc{Smáll Câps. Ii}
\textit{\fakesc{Smáll Câps. Ii}}
\end{document}
Just for comparison, what we can do in OpTeX:
\fontfam[dejavu]
\def\fakecaps#1{\def\tmp{#1}\replstring\tmp{ }{{ }}%
{\ea\let \ea\fupper \the\font \uccode`'=`'
\setfontsize{mag.8}\setff{+upper;embolden=1.1}\setwordspace{1.25}\fontsel
\ea\foreach\tmp\do{\ifnum\uccode`##1=`##1{\fupper##1}\else ##1\fi}}}
Normal text.
\fakecaps{Aren't it. Šmudla, že.}
\bye
See also OpTeX trick 0107.
Here is a code based on egreg's answer, which automatically detects the current font before passing the value to the command.
EDIT:
I corrected the issue with WordSpace by using \newfontfamily instead of obsolete package option.
The apostrophe and comma not being rendered properly has been fixed thanks to user94293's answer.

As a follow-up to the accepted answer, the apostrophe issue can be addressed by defining instead
\cs_new_protected:Nn \__krebs_smartsc_letter:n
{
\int_compare:nTF { \char_value_lccode:n { `#1 } = `#1 }
{
\char_uppercase:N #1
}
{
{\currentfont #1}
}
}
It checks whether lowercases match (instead of checking uppercases).
\char_value_lccode instead of ... uccode is a great idea for apostrophes and punctuation, it solves it, I'll update my answer thank you very much!

Since you are using fontspec: If you need to fake small caps, you might wish to use the FakeStretch optional argument. See the fontspec manual. You might also wish to increase the letter spacing, but I believe that FakeStretch already helps you there.
If you downscale uppercase letters, to make fake small caps, then the weight (thickness) of the characters also decreases in proportion. You can compensate in the horizontal direction using FakeStretch. Compensation should not be exactly the inverse of the shrinkage, since small caps are normally slightly lighter than uppercase.
Fontspec also has FakeBold but I am reluctant to use it. I do not know its algorithm. At least in some font editors, using the equivalent of FakeBold runs the risk of generating self-crossing or ambiguous glyph outlines. But FakeStretch is merely a one-dimensional scale, so that should not cause any problems.
FakeStretch will leave the horizontal bars (and serifs) alone, so they will be too thin. But this may escape notice. Depends on the font.
On a related note, some folks like to put acronyms in "medium caps" between small caps and uppercase. If you do that, it is usually better to upscale true small caps (if available) and unstretch the widths, rather than downscale uppercase and stretch the widths.
