Known issues with HTML to PDF conversion

(1) For best performance validate that the HTML follows the XHTML standard. The component will not perform as well as modern web browsers at correctly parsing HTML that is not well-formed, for example if a table row is missing an end tag ().

(2) Under some circumstances non-Latin characters will not render as expected. For example, a set of predefined fonts are installed for languages like Chinese, but if the HTML does not specify a commonly known font the component under some circumstances will fail to determine which font to use and the character won’t be displayed properly.

(3) Each html file is coverted to a A4-size PDF. When a single HTML line width is greater than the A4-size width the line will be truncated in the PDF rendering.
