UTF-16 is not supported

Hi

I have this error:

>fortcom: Severe: Source file format UTF-16 is not supported. Convert to a supported format.

, after I copy some messages (some Chinese and also some Russian codes inside I guess) from my email (I comment them).

I restore it, however, I still have this error.

Even I delete them all, I still have this error.

It is very very weird.

 

Mike

Quite silly to reply to myself.

I finnaly edit a new file and copy my original file step by step.

And it works.  Until, I don't know why.

I find the sizes of two same file (one is copied by the other) are different.

One is 41 k, and the other one is 21 k.

It must have something inside and invisible.  :)

UTF-16, also known as "wide characters", or simply but imprecisely as "Unicode", is character encoding where 2 bytes are assigned to every character (as opposed to common, "ASCII" or UTF-8, or other types of encoding, where 1 byte is assigned). With UTF-16, you can get 65536 different letters simultaneously, but at the obvious cost of using twice as much space. Fortran compiler (like many others) doesn't like UTF-16 encoded files, as it said.

Much of the underlying OS infrastructure in Windows is, actually, based on UTF-16. When you copy/paste text between Unicode-aware and unaware applications, lots of conversions take place and strange things occasionally happen.

What probably happened is that you pasted some UTF-16 encoded text from the web page, Visual Studio recognized that your file now has a wider range of characters than 256 and automatically saved it as UTF-16 (or asked, but you didn't pay too much attention).

In the Save As dialog of Visual Studio 200x, there's option "Save with Encoding", hidden below the arrow attached to the "Save" button.

Hi, Jugoslav

Yes, you are right.

After I save it as (using Advanced Save Options) "Unicode (UTF-8 with signature)", the program is ok now.

Now I can keep on doing my job.

Thank you very much indeed.
