Why do I receive an "Unable to open the requested feature, Error Code -6: ERR_FILE_NOT_FOUND" error when launching the R2020a Installer?

When launching the installer I receive the following error:

For R2020a and newer, this error will occur if installer or installation files are located in a directory containing accented or double-byte (e.g. Korean) characters. 

For example:

C:\Users\테스트

or

C:\Users\müller

The current workaround for this error is to move the installer or installation files to a folder not containing any accented or double-byte characters in it's path, such as:

C:\MATLAB
