utf 8 - Convert a text file to UTF8 in D -


i'm attempting use phobos standard library functions read in valid utf file (utf-8, utf-16, or utf-32) , utf-8 string (aka d's string). after looking through docs, concise function think of is

using std.file, std.utf;  string readtoutf8(in string filename) {     try {         return readtext(filename);     }     catch (utfexception e) {         try {             return toutf8(readtext!wstring(filename));         }         catch (utfexception e) {             return toutf8(readtext!dstring(filename));         }     } }

however, catching cascading series of exceptions seems extremely hackish. there "cleaner" way go without relying on catching series of exceptions?

additionally, above function seems return one-byte bom in resulting string if source file utf-16 or utf-32, omit given it's utf-8. there way omit besides explicitly stripping it?

one of questions answers other: bom allows identify exact utf encoding used in file.

ideally, readtext you. currently, doesn't, you'd have implement yourself.

i'd recommend using std.file.read, casting returned void[] ubyte[], looking @ first few bytes see if start bom, cast result appropriate string type , convert string (using toutf8 or to!string).
