[TYPO3] Saving UTF8 files in BE

[Andrew Plank]

Hi,

When I'm editing locallang.xml files in the BE using Quixplorer, it 
doesn't get saved as a UTF8 file, so I get the error about the locallang 
file not being a proper langage file...

What is it that dictates which character encoding is used when saving 
files? Is it Quixplorer? Some TS constant? Or is it more fundamental at 
a PHP/OS level?

Ideally somewhere in TS I could do plugin.t3quixplorer.charset = UTF8

Any advice/ideas?
