Sig and Bio user preferences test. The user preferences page (https://dev.soylentnews.org/users.pl) describes these fields as:

Sig: Appended to the end of comments you post. 120 chars.

Bio: This information is publicly displayed on your user page. 255 chars.

These tests ensure that we support that number of characters and not just that number of bytes. Specifically, characters greater than U+007f require 2 or more octets (bytes) to represent them as UTF-8 chars, as follows (taken from https://tools.ietf.org/html/rfc3629):

Char. number range  |        UTF-8 octet sequence
   (hexadecimal)    |              (binary)
--------------------+---------------------------------------------
0000 0000-0000 007F | 0xxxxxxx
0000 0080-0000 07FF | 110xxxxx 10xxxxxx
0000 0800-0000 FFFF | 1110xxxx 10xxxxxx 10xxxxxx
0001 0000-0010 FFFF | 11110xxx 10xxxxxx 10xxxxxx 10xxxxxx

    I updated my preferences (https://dev.soylentnews.org/users.pl [soylentnews.org])so that my Sig contained:

    Mauris in tortor ac metus suscipit adipiscing non eget mauris. Sed velit mauris, consectetur in lobortis sed, commodo net

    Then I clicked on the 'Save User' button and saw this value was silently truncated to 120 chars, as follows:

    Mauris in tortor ac metus suscipit adipiscing non eget mauris. Sed velit mauris, consectetur in lobortis sed, commodo ne

    Starting Score:    1  point
    Karma-Bonus Modifier   +1  
    Total Score:   2

    The Sig on the parent comment was displayed as:

    Mauris in tortor ac metus suscipit adipiscing non eget mauris. Sed velit mauris, consectetur in lobortis sed, commodo ne

    Success.
