Redis排序忽略空格

Question

尝试使用以下命令在redis中进行排序：

sort ids by messages|*->ss ASC LIMIT 0 10 GET messages|*->ss ALPHA

消息| .ss是字符串值 输出：

1 that of
a community in
add ensuring so      #this should be at the end before b...
against entitled and #this should be at the end before b...
a give and
a he can
a objective world
a of like
a to I
birthday moment daily

如您所见，空格被忽略。我期待那些线条在“每日生日时刻”之前结束。

add ensuring so
against entitled and

试图设置LC_ALL = C和LC_COLLATE = C环境变量，没有帮助。
