I was having troubles (and still do) trying to open links like [[Cyrillic link|file:///g:\!Notebook\Записная1]]. So I tried to use it in Unicode [[Cyrillic link|file:///G:/!Notebook/%D0%97%D0%B0%D0%BF%D0%B8%D1%81%D0%BD%D0%B0%D1%8F1]] but with the same result.
I asked people here on the forum and they said they have no problem with those. So I just decided that's just my local system problem. Untill I tried opening my TW in a browser, not in the TiddlyDesktop that I was usually working in. And everything works just fine! Both ways: either in Cyrillic letters or with Unicode.
So my petition to those who develop TiddlyDesktop: could you make it handle links to local folders in Cyrillic and Unicode in general the same way it handles links in Latin?
