Subject: [PATCH 1/2] Update allowanylanguage.js

Script was not working when testing in PDI.
With help of AI wrote a script that has the same purpose, has a logical order, is well commented, and works (validated this on my PDI).

-Allow Any Language Character Remove Special Characters, Can be used to verify valid names. Sorry Elon Musk's First born.
+# trimNonCharacters
+
+## Description
+
+This JavaScript function removes special characters from strings while preserving valid characters from multiple language groups.
+
+Useful for validating names or user input in internationalized applications.
+
+> Sorry, Elon Musk's firstborn — `X Æ A-12` might not make it through unscathed.
+
+## Features
+
+- Removes punctuation, emojis, and symbols
+- Preserves:
+  - Basic Latin letters (A–Z, a–z)
+  - Digits (0–9)
+  - Whitespace and parentheses
+  - Accented characters (e.g., é, ñ, ü)
+  - Characters from:
+    - Central/Eastern European languages
+    - Cyrillic (Russian, Ukrainian)
+    - Greek
+    - Arabic
+    - Hindi/Sanskrit (Devanagari)
+    - Chinese, Japanese, Korean (CJK ideographs)
+
+## Compatibility
+
+- Fully compatible with **ServiceNow background scripts**
+- Avoids unsupported features like:
+  - Unicode property escapes (`\p{L}`)
+  - Multi-line regex literals
+  - Inline comments inside regex
+
+## Usage
+
+Change the input string to your own text/variable, call the function with the input, handle the result:
+```
+var input = "Hello, мир! Γειά σου κόσμε! مرحبا بالعالم! नमस्ते दुनिया! 你好，世界！";
+var cleaned = trimNonCharacters(input);
+gs.info("Cleaned: " + cleaned);
+```
+## Customization
+Language support is modular. Unicode ranges are defined in an array and can be commented out or modified as needed:
+```
+var allowedRanges = [
+  "a-zA-Z0-9()",     // Basic Latin
+  "\\s",             // Whitespace
+  "\\u00C0-\\u00FF", // Western European
+  "\\u0100-\\u017F", // Central/Eastern European
+  "\\u0400-\\u04FF", // Cyrillic
+  "\\u0370-\\u03FF", // Greek
+  "\\u0600-\\u06FF", // Arabic
+  "\\u0900-\\u097F", // Hindi/Sanskrit
+  "\\u4E00-\\u9FFF"  // Chinese, Japanese, Korean
+];
+```
