Then Sylpheed is just broken.  It shouldn't look at the locale name,
but instead at nl_langinfo (CODESET) (the same can be queried from
locale -k LC_CTYPE | grep ^charmap=
).
And, no matter what spelling you use in the .* part of locale name
in environment, CODESET is the same:

LC_ALL=en_US.UTF-8 locale -k LC_CTYPE | grep charmap
charmap="UTF-8"
LC_ALL=en_US.utf8 locale -k LC_CTYPE | grep charmap
charmap="UTF-8"
LC_ALL=en_US.utf-8 locale -k LC_CTYPE | grep charmap
charmap="UTF-8"
LC_ALL=en_US.UTF_8 locale -k LC_CTYPE | grep charmap
charmap="UTF-8"
