Re: Copy/past doesn't work sometimes in Chrome semifixed

2019 posts

I think I found a solution.

But first the problem, which preferably would be fixed in the Pharo VM but I have no idea how to contribute there or if this is actually correct/wrong:

After a lot of debugging and trying to figure out why paste from Google Chrome(ium) isn't working in Linux I found out that the default encoding isn't unicode.

According to this the default should be UTF-8
platforms/unix/vm/sqUnixMain.c:1493 printf(" --textenc <enc> set encoding for external text (default: UTF-8)\n");

however by default it is set to 0
platforms/unix/vm/sqUnixMain.c:127 int textEncodingUTF8= 0; /* 1 if copy from external selection uses UTF8 */

and only set to 1 if it is explicitly provided (--textenc UTF-8)
platforms/unix/vm/sqUnixMain.c:1452     else if (!strcmp(argv[0], "--textenc"))
    {
    char *buf= (char *)malloc(strlen(argv[1]) + 1);
    int len, i;
    strcpy(buf, argv[1]);
    len= strlen(buf);
    for (i= 0; i < len; ++i)
        buf[i]= toupper(buf[i]);
    if ((!strcmp(buf, "UTF8")) || (!strcmp(buf, "UTF-8")))
        textEncodingUTF8= 1;
    else
        setEncoding(&uxTextEncoding, buf);
    free(buf);
    return 2;
    }

--

So the (temporary) fix is quite simple: specify the --textenc encoding when launching Pharo. :)

Ok, so I'll have to get used to it or switch to another web browser

Thanks for your answers.
