I have created a series of files from python that creates .csv files for InDesign. The files are written in (utf-16) format. As shown in the first picture when I select a csv data source the special characters show up. I then load them as unicode dellimited by commas on my pc (see 2. Choose Data Source Input Options). I populate them into a form, which shows the fields I am trying to work with (Comments and Counter) - (see 3. Populate Data Merge Fields)
When I look at the output (6. Result Missing UTF-16 Emoji characters) any specail characters do not display while standard text (ie the counters, which are numbers) and text displays.
I am using InDesign 17.2.1 x64 on a Dell workstation with 256 GB of RAM running Windows 10 x64
