Hola, parece haber un problema cuando la aplicación carga una publicación que contiene caracteres no en inglés (por ejemplo, caracteres chinos 中文). Supongo que podría estar relacionado con la función de nombres Unicode de Discourse (Unicode usernames and group names ) y he abierto un issue para publicar el registro detallado del error en el repositorio de 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')

which may be related to: https://github.com/lexiconhq/lexicon/blob/e0a61d2f535181525edb3c1312aed51976c6ddec/frontend/src/screens/PostDetail.tsx#L357
## 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!
