如何将Char转换为Int?

所以我有一个String整数，看起来像"82389235"，但是我想遍历它，将每个数字分别加到MutableList上.但是，当我按照自己认为的方式进行处理时:

So I have a String of integers that looks like "82389235", but I wanted to iterate through it to add each number individually to a MutableList. However, when I go about it the way I think it would be handled:

var text = "82389235"

for (num in text) numbers.add(num.toInt())

这会将与字符串完全无关的数字添加到列表中.但是，如果我使用println将其输出到控制台，它会很好地遍历字符串.

This adds numbers completely unrelated to the string to the list. Yet, if I use println to output it to the console it iterates through the string perfectly fine.
