2. General Conformance Check
3. Address: http://www.infineon.com/cms/en/product/microcontroller/32-bit-tricore-tm-microcontroller/aurix-tm-family/aurix-tm-family-%E2%80%93-tc23xla/SAK-TC234LA-32F200F+AB/productType.html?productType=5546d46250cc1fdf0150cdc1ff1609c5#ispnTab6
4. Notice results fail to produce a section for the Nu Html Checker

The html check result will contain an error such as:

... { type: "error", lastLine: 422, lastColumn: 28, message: "Forbidden code point U+0080.", extract: "udgetary Price �€/1k ", hiliteStart: 15, hiliteLength: 1 }, ...
