The error message "SyntaxError: Invalid character '\u2118'" suggests that there's an invalid character (in this case, U+2118, which is the "SCRIPT CAPITAL P" character) in your JavaScript file. This issue could be caused by a number of reasons such as incorrect file encoding, a typo, or corruption in the JavaScript file.
Here are a few steps you can take to troubleshoot and resolve this issue:
1. Check File Encoding
Even though you mentioned that the encoding is set to UTF-8, it’s good to double-check that the JavaScript file is indeed saved with UTF-8 encoding.
You can use the file command to check the file encoding:
file your_script.js
Ensure the output indicates that the file is in UTF-8 encoding. If not, convert it to UTF-8 using tools like iconv:
iconv -f <current_encoding> -t utf-8 your_script.js -o your_script_utf8.js
2. Inspect the JavaScript File
Manually inspect the JavaScript file for any non-standard or invisible characters. You can use a text editor that supports viewing and editing in different encodings (like vim, nano, or a GUI editor).
You can also use tools like cat -v to visualize non-printable characters:
cat -v your_script.js
3. Re-download the JavaScript File
If the JavaScript file is being downloaded from an external source, it might be worth re-downloading it to ensure it hasn’t been corrupted.
4. Sanitize the JavaScript File
You can write a small script to sanitize your JavaScript file by removing non-UTF-8 characters. Here is an example using Python:
import re
def remove_non_utf8_chars(file_path):
with open(file_path, 'r', encoding='utf-8', errors='ignore') as file:
content = file.read()
sanitized_content = re.sub(r'[^\x00-\x7F]+', '', content)
with open(file_path, 'w', encoding='utf-8') as file:
file.write(sanitized_content)
remove_non_utf8_chars('your_script.js')
5. Verify JavaScript Syntax
Ensure there are no syntax errors or typos in your JavaScript file. Sometimes, a misplaced character or typo can lead to such errors.
6. Use a Different Version of WebKitGtk
Since you are using an older version of WebKitGTK (4.0.37), it might be worthwhile to try a newer version if possible. There might be bug fixes or improvements in handling character encodings in newer versions.
Example Code in C (Using WebKitGTK)
Here’s a simple example of how you might load a web page with a JavaScript file in a WebKitGTK application:
#include <gtk/gtk.h>
#include <webkit2/webkit2.h>
int main(int argc, char *argv[]) {
gtk_init(&argc, &argv);
GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_default_size(GTK_WINDOW(window), 800, 600);
WebKitWebView *web_view = WEBKIT_WEB_VIEW(webkit_web_view_new());
gtk_container_add(GTK_CONTAINER(window), GTK_WIDGET(web_view));
WebKitSettings *settings = webkit_web_view_get_settings(web_view);
webkit_settings_set_default_charset(settings, "UTF-8");
g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
webkit_web_view_load_uri(web_view, "file:///path/to/your/local/file.html");
gtk_widget_show_all(window);
gtk_main();
return 0;
}
In the HTML file, ensure you specify UTF-8 encoding in the meta tag:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Test</title>
<script src="your_script.js"></script>
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>
Following these steps should help you identify and fix the issue with the invalid character in your JavaScript file.
