Flex FileReference prohibited characters -

the utilize of filereference has constraint on valid characters. error: error #2087: filereference.download() file name contains prohibited characters. fine since guess restriction comes underlying file scheme anyway is there such things generic way trim / replace prohibited characters? clarity after like: var dirty:string = "eat !@##$%%^&&*()\/";.txt var clean:string = dirty.replaceallprohibitedcharacters(); not looking os specific regular expressions, cross platform solution.

the list of disallowed characters not alter depending on underlying os, fixed list. documentation filereference.download() list of disallowed characters is:

/\:*?"<>|%

edit: looks @ isn't allowed either.

if want remove characters arbitrary string can this:

var validfilename:string = invalidfilename.replace(/[\/\\:*?"<>|%@]/g, "");

if want replace them else, alter sec parameter replace().

edit: added @ character; escaped / character.
