How to split a Chinese string by character?

Question

I have a string containing mostly chinese characters, like so: ``` string sentence = "我想找到从夏洛特飞往拉斯维加斯，让站在圣路易斯"; ``` How can I split the sentence by character? Ultimately, I want to be able to take my string, and write it to a file with each character being on its own line, like so: ``` 我 想 找 到 从 夏 洛 特 飞 往 拉 斯 维 加 斯 ， 让 站 在 圣 路 易 斯 ``` I tried doing this: ``` StringBuilder s = new StringBuilder(); foreach (char character in sentence.ToCharArray()) { s.Append(character + '
'); } string output = s.ToString(); StreamWriter writer = new StreamWriter("test.txt", false, Encoding.UTF8); writer.Write(output); writer.Close(); ``` ...but for whatever reason, instead of writing chinese characters, it writes ``` 29252242105020184228092794129315391442445825299260413251021162260416530235763314592232222317363452614126041 ``` ...to the file instead. However, doing ``` StreamWriter writer = new StreamWriter("text.txt", false, Encoding.UTF8); writer.Write(sentence); writer.Close(); ``` ...does successf…

Accepted Answer

I think the problem may be that (character + '
'); is being interpreted as an integer. Perhaps trying adding a cast to that line or making two seperate appends like so:

```
s.Append(character);
s.Append('
');
```
