python - Convert raw byte string to Unicode without knowing the codepage beforehand -


when using right-click menu context, windows passes file path raw (byte) string type.

for example:

path = 'c:\\mydir\\\x99\x8c\x85\x8d.mp3'

many external packages in application expecting unicode type strings, have convert unicode.

that easy if we'd known raw string's encoding beforehand (in example, cp1255). can't know encoding used locally on each computer around world.

how can convert string unicode? perhaps using win32api needed?

no idea why might getting dos code page (862) instead of ansi (1255) - how right-click option set up?

either way - if need accept arbitrary unicode character in arguments can't python 2's sys.argv. list populated bytes returned non-unicode version of win32 api (getcommandlinea), , encoding never unicode-safe.

many other languages including java , ruby in same boat; limitation comes microsoft c runtime's implementations of c standard library functions. fix it, 1 call unicode version (getcommandlinew) on windows instead of relying on cross-platform standard library. python 3 this.

in meantime python 2, can calling getcommandlinew it's not pretty. can use commandlinetoargvw if want windows-style parameter splittng. can win32 extensions or plain ctypes.

example (though step of encoding unicode string utf-8 bytes best skipped).

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
