encoding - How windows notepad interpret characters -

-

i wondering how windows interpret characters, instance:

i maked file hexeditor 3 bytes e3 81 81. bytes "ぁ" character encoded utf-8.

i open notepad , display "ぁ"

i dont specified encoding of file, created bytes. , notepad interpret correctly.

is notepad guessing encoding is? or hex editor saving bytes specific encoding.

if file contains these 3 bytes, there no information @ encoding use.

a byte byte, , there no way include encoding information in it. besides, hex editor doesn't know intended decode data text.

notepad uses ansi encoding, if reads file utf-8 has guess encoding based on data in file.

if save file utf-8, notepad put bom (byte order mark) ef bb bf @ beginning of file.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
