--- Comment #1 from Tim Shen <timshen at gcc dot gnu.org> ---
    std::string s = "\"João Méroço\" <email@isp.com>";

...is not what you want. It is not an decoded unicode string, but just "a
sequence of bytes":

    std::string s = "\"João Méroço\" <email@isp.com>";
    for (const auto& it : s) {
    std::cout << it << "\n";
    }
...print:
"
J
o

�
o

M

�
r
o

�
o
"

<
e
m
a
i
l
@
i
s
p
.
c
o
m
>

I don't know much about unicode support status in the standard library. @Jon,
can you put a comment?

Martin, please use present tense in your Changelog entries, as specified by the
GNU Coding Standard:

    * ipa-icf-gimple.c (func_checker::compare_gimple_switch): Add missing
    checking for CASE_LOW and CASE_HIGH.
