non latin characters before the code block break highlighting

[a-kempka]

Describe the bug using non latin characters such as ä ö ü ß breaks code highlighting

To Reproduce Steps to reproduce the behaviour:

1. create label with the following HTML

   <h3>Umlaut breaks highlighting</h3>
   <p>code highlighting breaks when using non latin characters: ä ü ß ö - each character cuts makes one char of the not to be highlichted code tag appear</p>
   <pre><code>
   # This is a Python program that calculates the sum of two numbers
   num1 = 5
   num2 = 10
   sum = num1 + num2
   print("The sum of", num1, "and", num2, "is:", sum)
   </code>
   </pre>

   The code and pre tag are highlighted as well. The more umlauts you insert, the more characters of the parts after the code are displayed, i.e. the closing tags (code and pre) are highlighted and break the subsequent HTML.

Expected behaviour The code highlighting should end at "sum)"

Thank you for the quick fix. Umlauts don't interfere with SynHi now.
