Is the tick or acute accent character (´) used for anything in Linux shell?

We know that the backtick character is used for command substitution:
chown `id -u` /mydir
Which made me wonder: is the tick character ´ used for anything in the Linux shell?
Note: incidentally, command substitution can also be written more readably aschown $(id -u) /mydir

I was unsure of the name, but I thought´is called acute accent only when used as a diacritic (and, conversely,`is called grave accent). When used alone, as the latter is a backtick, it seemed natural for the former to be called a tick or forward tick (please let's not call it reverse backtick). I've modified the title question to include your note.

The character sets used historically with Unix, including ASCII, don’t have a tick character, so it wasn’t used. As far as I’m aware no common usage for that character has been introduced since it’s become available; nor would it, since it’s not included in POSIX’s portable character set.
` was apparently originally included in ASCII (along with ^ and ~) to serve as a diacritic. When ASCII was defined, the apostrophe was typically represented by a ′-style glyph (“primeâ€Â, as used for minutes or feet) rather than a straight apostrophe ', and was used as a diacritic acute accent too.

"Presumably ´ wasn’t considered common enough to make the cut (despite its widespread use in non-American languages)." Touché.

Characters outside the POSIX portable character set (a subset of ASCII) would not be used in the syntax of shells, as their encoding would typically vary between locales (and may not be found in some including the C locale). For instance, on a GNU system,´is 0xB4 in a fr_FR.iso88591 locale, 0xC2 0xB4 in a fr_FR.UTF-8 and doesn't exist in the C locale.
