Go 语言的字符使用UTF-8 编码
- *英文字母
1个字节, 汉子3个字节
golang的字符称为rune，等价于C中的char，可直接与整数转换
<span class="hljs-keyword">var c <span class="hljs-keyword">rune=<span class="hljs-string">'a'
<span class="hljs-keyword">var i <span class="hljs-keyword">int =<span class="hljs-number">98
i1:=<span class="hljs-keyword">int(c)
fmt.Println(<span class="hljs-string">"'a' convert to",i1)
c1:=<span class="hljs-keyword">rune(i)
fmt.Println(<span class="hljs-string">"98 convert to",<span class="hljs-keyword">string(c1))
</span></span></span></span></span></span></span></span></span></span></span>
rune实际是整型，必需先将其转换为string才能打印出来，否则打印出来的是一个整数
c:=<span class="hljs-string">'a'
fmt.Println(c)
fmt.Println(<span class="hljs-keyword">string(c))
fmt.Println(<span class="hljs-keyword">string(<span class="hljs-number">97))
</span></span></span></span>
输出
<span class="hljs-number">97
<span class="hljs-string">a
<span class="hljs-string">a</span></span></span>
