Please see the following links for more information regarding how to setup Chinese (Simplified) in Web-Tier:
Also, you can control the position/size of that (within the toolbar) through this file/setting on the server:
C:\Program Files (x86)\IndySoft\Clients\www\software\html5\settings.js
Search on this setting - it will likely be defaulted as:
W.softLanguageBar = { "device": "all", "font_size_sel": "100%", "font_color_sel": "white", "font_color_unsel": "black", "height": "45%", "width": "70px", "left": "90%", "top": "90%" };
For instance, you could modify the font_size_sel to be a bit smaller (75%) and left position at 10% - so less likely to be covering other text in the IndySoft header:
W.softLanguageBar = { "device": "all", "font_size_sel": "75%", "font_color_sel": "white", "font_color_unsel": "black", "height": "45%", "width": "70px", "left": "10%", "top": "90%" };
More importantly - make sure the "device" setting there is "all" so it will show on all device types (if desired)
Lastly, Windows 2016 has a bug related to display of Chinese (Simplified) and requires a registry change - see this link for details: https://support.microsoft.com/en-ae/help/4040941
