#3848: purple_markup_unescape_entity doesn't escape hexadecimal references
---------------------------+------------------------------------------------
 Reporter:  BigBrownChunx  |       Type:  patch
   Status:  new            |   Priority:  minor
Component:  libpurple      |    Version:  2.2.2
 Keywords:                 |    Pending:  0    
---------------------------+------------------------------------------------
 The libpurple function purple_markup_unescape_entity() can convert
 entities in the decimal form © but not in the hexadecimal form ©

 The implications of this are that when using purple_markup_strip_html() to
 convert Adium UTF-8 messages, the hexadecimal entities that it sends
 aren't converted.

 A solution to this is to convert
 {{{
 else if(*(text+1) == '#' && (sscanf(text, "&#%u;", &pound) == 1) &&
                         pound != 0 && *(text+3+(gint)log10(pound)) == ';')
 {
 }}}
 to
 {{{
 else if(*(text+1) == '#' && ((sscanf(text, "&#%u;", &pound) == 1) ||
                         (sscanf(text, "&#x%x;", &pound) == 1)) &&
                         pound != 0 && *(text+3+(gint)log10(pound)) == ';')
 {
 }}}
