I use Greenshot that automatically saves screenshots with window titles in their names. For example, when I was browsing App Store, I took a screenshot and it was saved like this:
However, when I tried to open this image, I get this error:
It wasn’t hard to realize that some strange character may exist in the name, because I can open it once I pressed
F2 and renamed it to something else. But what exactly was wrong with the name?
I copied the name to a text file, and showed a hex dump:
Offset: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
E2 80 8E? A Left-to-right mark in UTF-8.
C2 A0? A Non-breaking space in UTF-8.
