简书链接:kotlin遍历打印所有中文unicode或Ascii
文章字数：1005,阅读全文大约需要4分钟
unicode实际上是ascii编码表的16进制 ，不过ascii码表只有127个，
那么换行符Line feed \n转换为 unicode 也就是把\n对应的10进制 是 10 转换为16进制就是A,
就是 \u000A 下面包含我的名字，哈哈

1
println("i am  line feed "+'\u000A'+" hello"+'\u7F57'+'\u6b63')

    for(value in '0'  .. 'z'){
        println("ASCII CHAR ${value}  DEC ${value.toByte()} HEX ${Integer.toHexString(value.toInt()).toUpperCase()}")
    }

    println("------------------------------")
//all ascii
    for(value in 0  ..127){
        println("ASCII CHAR ${value.toChar()}  DEC ${value} HEX ${Integer.toHexString(value.toInt()).toUpperCase()}")
    }
    println("------------------------------")
    // chinese unicode
    for(value in 0x4e00  ..0x9fa5){
        println("ASCII CHAR ${value.toChar()}  DEC ${value.toInt()} HEX ${Integer.toHexString(value).toUpperCase()}")
    }

0-127 其他就不输出了，太长了我擦
