MYSQL：区分重音但不区分大小写的最佳 utf 设置
[英]MYSQL: best utf setting for ACCENT sensitive but CASE insensitive
问题描述
For example, ἐν or Ἐν are the same, but should be distinguished from ἕν/Ἓν.
例如，ἐν 或 Ἐν 相同，但应与 ἕν/Ἓν 区分开来。 I've tried utf8_bin which seems to be the closest, but is also case sensitive.我试过 utf8_bin ，它似乎是最接近的，但也区分大小写。
