Olá, parece haver algum problema quando o aplicativo carrega uma postagem que contém caracteres não em inglês (por exemplo, caracteres chineses 中文). Acredito que isso possa estar relacionado ao recurso de nomes Unicode do Discourse (Unicode usernames and group names ) e já abri uma issue para registrar o log de erro detalhado no repositório do GitHub:

## Detailed Issue
Hi, thank you for creating such an awesome app for the discou… rse instance! Unfortunately, when I tried to connect the app to my own discourse instance, I found some problems that may be related to character encoding:
When the username or the content of the post contains unicode characters (e.g. Chinese characters), the application will throw an exception as follows:
<details>
<summary>Exception</summary>
```
TypeError: null is not an object (evaluating 'cacheUser.username')

## Ways to reproduce
- Set the `PROSE_DISCOURSE_HOST` of prose to `https://springboot.io/` (which is a chinese springboot discourse fourm)
- start the app by `npm run --prefix frontend start`
- Click any post that is written in Chinese.
Which could lead to the exception of the application.
Thanks in advanced!
