UTF-8 HTML Documents
AlphaTrust® e-Sign supports the use of HTML / XHTML documents encoded in UTF-8 format. UTF-8 is an encoding scheme for supporting Unicode text using 8 bit characters. This enables the full range of 16-bit Unicode characters to be used in HTML documents.
To use Unicode text in AlphaTrust® e-Sign source document, you must save the HTML document in UTF-8 format. This is the international standard for Unicode HTML documents. 16-bit Unicode HTML documents are not supported by AlphaTrust® e-Sign. You MUST include the proper "Content-Type META tag for UTF-8 in your HTML source document or AlphaTrust® e-Sign may not interpret the input document properly. The correct META tag for UTF-8 is:
META tag for UTF-8 Example
html
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
INFO
Source documents validated by AlphaTrust® e-Sign will be saved as ASCII text and character values above 127 (0x 007F) will be converted to HTML numeric entity references and the META content-type will be content="text/html; charset=iso-8859-1". This is done to support the widest range of browsers (HTML user agents) on the market. Many older browsers and small device browsers can't properly process UTF-8 encoded HTML pages.
