- /* The MimeInlineText class is the superclass of all handlers for the
- MIME text/ content types (which convert various text formats to HTML,
- in one form or another.)
-
- It provides two services:
-
- = if ROT13 decoding is desired, the text will be rotated before
- the `parse_line' method it called;
-
- = text will be converted from the message's charset to the "target"
- charset before the `parse_line' method is called.
-
- The contract with charset-conversion is that the converted data will
- be such that one may interpret any octets (8-bit bytes) in the data
- which are in the range of the ASCII characters (0-127) as ASCII
- characters. It is explicitly legal, for example, to scan through
- the string for "<" and replace it with "<", and to search for things
- that look like URLs and to wrap them with interesting HTML tags.
-
- The charset to which we convert will probably be UTF-8 (an encoding of
- the Unicode character set, with the feature that all octets with the
- high bit off have the same interpretations as ASCII.)
-
- #### NOTE: if it turns out that we use JIS (ISO-2022-JP) as the target
- encoding, then this is not quite true; it is safe to search for the
- low ASCII values (under hex 0x40, octal 0100, which is '@') but it
- is NOT safe to search for values higher than that -- they may be
- being used as the subsequent bytes in a multi-byte escape sequence.
- It's a nice coincidence that HTML's critical characters ("<", ">",
- and "&") have values under 0x40...
