/*As illustrated by this example, the text, enclosed with single quotes, must be passed to a function call return escape(). Attention: Single quotes or apostrophes, respectively, inside the tooltip text itself each must be escaped with a backslash. Example:
return escape('This text won\'t create an error.');
Characters not found in the normal alphanumeric character set, inevitably must be specified using character entities. For instance, use &quot; instead of " or &Ouml; instead of Ö. Consider the following three irregularities: Write & amp; instead of &amp;, & lt; instead of &lt; (displaying as <) and & gt; instead of &gt; (displaying as >).
