Today is 25\textcelsius.
What you're using here is an emulation inside a 7- or 8-bit "plain
old" LaTeX. It's based on the use of virtual fonts and very irregular
font encodings. This should not be used with XeTeX.
The DEGREE CELSIUS character exists in hundreds of fonts, for example
Latin Modern, Libertine, DejaVu, Free{Mono|Sans|Serif}, TeX Gyre...
When it's not in your main font, serif or sans serif, you can make the
β an *active* character which comes from an auxiliary font.
\newfontfamily{\celsiusfont}{Free Serif}
\catcode"2103=\active
\defβ{{\celsiusfont\char"2103}}
or, more conservatively:
\newfontfamily{\celsiusfont}{Free Serif}
\newcommand{\cels}{{\celsiusfont β}}

If it does exist, it's out of date.
