Run script from the console with UTF-8 with BOM

[arteze]

From Linux I make a script with shebang:

#!/bin/node

// Code...

But when I transformed it to UTF-8 with BOM it does not run.

line 1: ���#!/bin/node: No such file or directory

Seeing this I just realized that it is a problem of the terminal and not of Node, but if I run it with Node, the problem is still.

node script.js

Answer in LxTerminal:

���#!/bin/node

Answer on Sakura:

#!/bin/node
 ^

This is expected behavior. See #27768

I see that one of the /test/fixtures folder works well.

curl -O https://raw.githubusercontent.com/nodejs/node/master/test/fixtures/utf8-bom.js

Hexdump of utf8-bom.js:

hexdump -C utf8-bom.js
00000000  ef bb bf 6d 6f 64 75 6c  65 2e 65 78 70 6f 72 74  |...module.export|
00000010  73 20 3d 20 34 32 3b 0a                           |s = 42;.|

• The file utf8-bom.js It works well.
• The file utf8-bom-shebang-shebang.js it does not work.
• The file utf8-shebang-bom.js also, it works perfect.

Hexdump of utf8-shebang-bom.js

hexdump -C utf8-shebang-bom.js
00000000  23 21 73 68 65 62 61 6e  67 0a ef bb bf 6d 6f 64  |#!shebang....mod|
00000010  75 6c 65 2e 65 78 70 6f  72 74 73 20 3d 20 34 32  |ule.exports = 42|
00000020  3b                                                |;|
00000021

Hexdump replicating my script:

hexdump -C ./test_she.js
00000000  ef bb bf 23 21 73 68 65  62 61 6e 67 0a 6d 6f 64  |...#!shebang.mod|
00000010  75 6c 65 2e 65 78 70 6f  72 74 73 20 3d 20 34 32  |ule.exports = 42|
00000020  3b 0a                                             |;.|

This fails while the one in fixtures works well.

I don't really know how to label this or who to ping, except @devsnek who worked on #27768
