I'm designing a Multi-language app and a major user group is Chinese speaking people with disability. The app will be on both iOS and Android. I don't speak or read any chinese language.
The app content for Chinese speaking users will be in Chinese Simplified (lang='zh-Hans'). We want to ensure that the content will be compatible, usable and understandable with the native screen reading software.
The app will provide information on emergency situations, so it's critical that important information not be lost in translation.
iOS If an iOS user is using VoiceOver and iOS is set to either Mandarin (China mainland), Mandarin (Taiwan) or Cantonese (Hong Kong) - How does Simplified Chinese read out? Is it understandable to native speakers of the above languages?
Android If an Android user is using TalkBack and Android is set to either Cantonese (Hong Kong), Chinese (China), Chinese (Taiwan) - How does Simplified Chinese read out? Is it understandable to native speakers of the above languages?
