Special characters in path cause problems in Windows
When non-standard characters, such as those in Portuguese, are included in directory or user names in a path, abstractions fail to load. The problem can be reproduced on a Windows 10 machine with purrdata 2.10. Please extract the attached file. There is a masterpatch.pd and a subpatch.pd file included in a directory called "pürdãtá". If you open the masterpatch.pd in Purrdata the embedded "subpatch" abstraction fails to load. If you rename the directory purrdata, it will.
Here is a table of accents/characters that mostly covers Portuguese (and probably covers Spanish):
I'd also add to this the following two common characters: º and ª
