UTF-8 character is '意'

推荐答案

chr 手册页中的一个快照，用于转换序数字符号成为UTF-8字节序列：

From the comments in the chr man page, one quick hack for turning an ordinal character number into a UTF-8 byte sequence:

function unichr($u) {
    return mb_convert_encoding('&#' . intval($u) . ';', 'UTF-8', 'HTML-ENTITIES');
}

// unichr(0x610F) -> "\xE6\x84\x8F"
