Optimized scheme sanitization performance by replacing regex operation with string replacement

The `replaceAll` method utilizes regular expressions, which can incur a performance cost due to the parsing required. In this modified code, uses `replace` method instead. This change often leads to faster execution, as in many cases the replacement is unnecessary. When it is needed, replace operates in a more straightforward, linear fashion, avoiding the overhead associated with regular expressions.
