Change description:

• Addition of the elimination of all UTF control characters from the created wrapped dlt-messages. Those characters were causing slow performance of some of the QT's API calls ( e.g. QFontMetrics::horizontalAdvance )
• Addition of the profiling to the "search view's" highlighting delegate ( turned off in production builds )
• Minor optimization regarding how the search model triggers updates of the "Search view"

Verification criteria:

• Manual verification on Windows OS
• All sanity checks on GitHub were passed
