MHonArc::CharEnt provides the main character conversion routine used by MHonArc for converting non-ASCII encoded message header data and text/plain character data into HTML. This module was initially written to just support 8-bit only charsets. However, it has been extended to support multibyte charsets.

All characters are mapped to HTML 4.0 character entity references (e.g. < >) or to Unicode numeric character entity references (e.g. ‾). Most modern browsers will support the Unicode references directly.

• This module relies on MHonArc's CHARSETALIASES resource for defining alternate names for charset supported.
• Most character conversion is done through mapping tables that are dynamicly loaded on a as-needed basis. There is probably room for optimization by trying to replace tables for charsets with algorithmic conversion solutions.
  
  UTF-8 conversion is done algorithmically.
• A main goal of this module is to convert raw non-ASCII data of various character sets to ASCII data using entity references for non-ASCII characters. This way, archive files will all be in ASCII, with modern compliant HTML browsers being able to handle the rendering of non-ASCII characters from the standard named and numeric character entity references.
  
  This does make reading the raw HTML source for non-English languages difficult, but this may be a non-issue with most users.
