Steps to Reproduce:
Make sure you have a company with an Umlaut in the company name. In my example I created a new company with a name of “Ümlaut”.
Create a new List gadget in the interactive dashboard on the Company entity (report: “Company List by Type” for example) and make sure to add the company name field as a column.
Use the [filter by] function in the gadget and filter by Company Name with the value “Ümlaut”.
There will be no result and the gadget stays empty.
Reproducable in 2017.R1.1 as well.
In relation use the [filter by] function a second time and filter by Company Name with the value “%mlaut”. This time the result will show the Company correctly.
