## FIXME: We should be able to deduplicate UTF-16 CFStrings too.
## Note that this string contains a null byte in the middle -- any dedup code
## we add should take care to handle this correctly.
## Technically, UTF-8 should support encoding null bytes too, but since we
## atomize the __cstring section at every null byte, this isn't supported. ld64
## doesn't support it either, and clang seems to always emit a UTF-16 CFString
## if it needs to contain a null, so I think we're good here.
