+===== Fix code copy =====
+The code copying replaces empty new lines with space (nbsp;) which are copied via selection or using the copy button. To replace the spaces with actual newlines, create conf/userscript.js and copy the following code, then save and hard-refresh the browser:
+<code javascript conf/userscript.js>
+jQuery(function() {
+    // Helper function to sanitize text formatting
+    function cleanDokuWikiCodeSpaces(text) {
+        return text
+            .replace(/\r\n/g, '\n')              // Standardize linebreaks
+            .replace(/\n[ \u00A0]+(?=\n)/g, '\n') // Remove spaces sitting completely alone on a line
+            .replace(/^[ \u00A0]+\n/, '\n')       // Clean leading blank lines
+            .replace(/\n[ \u00A0]+$/, '\n');      // Clean trailing blank lines
+    }
+    // FIX 1: Handle standard user manual mouse selections (Ctrl+C)
+    document.addEventListener('copy', function(e) {
+        const selection = window.getSelection();
+        if (selection.rangeCount > 0 && selection.anchorNode.parentElement.closest('pre.code')) {
+            let cleanedText = cleanDokuWikiCodeSpaces(selection.toString());
+            e.clipboardData.setData('text/plain', cleanedText);
+            e.preventDefault();
+        }
+    });
+    // FIX 2: Handle DokuWiki Core's Native Async Copy Button
+    document.addEventListener('click', function(e) {
+        // Targets DokuWiki's core copy elements (like .button-copy or data targets)
+        const btn = e.target.closest('button, a, div') && e.target.closest('[class*="copy"], [id*="copy"], [data-clipboard-target]');
+        if (!btn) return;
+        // Force monitor the system clipboard immediately following the click
+        let attempts = 0;
+        const maxAttempts = 10;
+        const checkAndCleanClipboard = setInterval(async () => {
+            attempts++;
+            try {
+                let currentText = await navigator.clipboard.readText();
+                // If clipboard contains data and has the raw space error, rewrite it immediately
+                if (currentText && (currentText.includes('\n ') || currentText.includes('\n\u00A0'))) {
+                    let cleanedText = cleanDokuWikiCodeSpaces(currentText);
+                    await navigator.clipboard.writeText(cleanedText);
+                    clearInterval(checkAndCleanClipboard); // Success, stop looping
+                }
+            } catch (err) {
+                // Clipboard permissions might delay slightly, keep trying
+            }
+            if (attempts >= maxAttempts) {
+                clearInterval(checkAndCleanClipboard); // Timeout safety fallback
+            }
+        }, 30); // Check every 30ms for immediate execution
+    });
+});
