release-fe5d8d61: suppress unused typedef warning
Summary: We're seeing the following compiler warnings: ``` unused type alias 'char_type' [-Werror,-Wunused-local-typedef] ``` and this breaks compilation since we build with `-Werror`. I haven't fully understood why & when this warning is triggered (it doesn't always trigger), but by adding a `[[maybe_unused]]` we can suppress the warning.
