We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
It's a pretty simple charset: the bottom 128 bytes (0x00-0x7F) are
standard ASCII, while the top 128 bytes (0x80-0xFF) are mapped to a
portion of the Unicode Private Use Area, specifically 0xF780-0xF7FF.
This is used by Google Maps for certain blobs.
This functions takes a user-provided decoder and will only use it if no
BOM is in the input.
If there is a BOM, it will ignore the given decoder and instead decode
the input with the appropriate Unicode decoder for the detected BOM.
This is only to be used where it's specifically needed, for example XHR
uses this for compatibility with deployed content. As such, it has an
obnoxious name to discourage usage.
This takes the input and sniffs it for a BOM. If it has the UTF-8 or
UTF-16BE BOM, it will return their respective decoder. Currently we
don't have a UTF-16LE decoder, so it will assert TODO if it detects
a UTF-16LE BOM. If there is no recognisable BOM, it will return no
decoder.
This commit adds a new process method to all Decoder subclasses which
do what to_utf8 used to do, and allows callers to customize the handling
of individiual UTF-8 code points through a callback. Decoder::to_utf8
now uses this API to generate a string via StringBuilder, preserving the
original behavior.
This patch changes get_standardized_encoding to use an Optional<String>
return type instead of just returning the null string when unable to
match the provided encoding to one of the canonical encoding names.
This is part of an effort to move away from using null strings towards
explicitly using Optional<String> to indicate that the String may not
have a value.
This encoding (a superset of ascii that adds in the cyrillic alphabet)
is currently the third most used encoding on the web, and because
cyrillic glyphs were added by Dmitrii Trifonov recently, we can now
support it as well :^)

way of representing file license information.

This was done with the `ambr` search and replace tool.
ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt *
This is a superset of ascii that adds in the hebrew alphabet.
(Google currently assumes we are running windows due to not
recognizing Serenity as the OS in the user agent, resulting
in this encoding instead of UTF8 in google search results)
This flag warns on classes which have `virtual` functions but do not
have a `virtual` destructor.
This patch adds both the flag and missing destructors. The access level
of the destructors was determined by a two rules of thumb:
1. A destructor should have a similar or lower access level to that of a
constructor.
2. Having a `private` destructor implicitly deletes the default
constructor, which is probably undesirable for "interface" types
(classes with only virtual functions and no data).
In short, most of the added destructors are `protected`, unless the
compiler complained about access.
