Lexicon: カスタマイズ可能なネイティブモバイルアプリ Discourseサイト向け

こんにちは、非英語の文字（例：中国語の文字中文）を含む投稿を読み込む際に、アプリケーションで何らかの問題が発生しているようです。Discourse の Unicode 名機能（https://meta.discourse.org/t/unicode-usernames-and-group-names/117737）に関連しているのではないかと推測しました。詳細なエラーログを GitHub リポジトリに提出するため、Issue を作成しました：

## 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') This error is located at: in PostDetail (at SceneView.tsx:122) in StaticContainer in StaticContainer (at SceneView.tsx:115) in EnsureSingleNavigator (at SceneView.tsx:114) in

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!
