Text formatting (ATX h1 header)

This is a flavored markdown processor for basic text styling.
Lines should end with two or more spaces
to have an intentional linebreak and not just continuing.

Text can be italic, bold with asterisks and underscores, italic and bold, striked through.
By adding decorators in the right place you achieve midwordemphasis and also mixed up emphasis.
Some escaping of formatting characters is possible with a leading \ as in bold * asterisk or striked ~~ through.
Subscript like H₂O, superscript like X² and marked text are available.
A custom markdown for this processor can make font larger or smaller

Substitutions (SETX h1 header)

Task lists can be created a well
where [ ] and [x]
are converted to html checkboxes

© © ® ® ™ ™ Ⓟ Ⓟ ± → will be replaced by their symbol
unless escaped: (c) (C) (r) (R) (tm) (TM) (p) (P) +- ->

Links (ATX h2 header)

Links will be replaced if not in safeMode, unless they are internal references

http://some.url, not particularly styled, just a detected protocol
a phone number: tel:012345678
[Styled link to markdown information](https://www.markdownguide.org)
<http://some.other.url> with brackets
[urlencoded link with title](http://some.url?test2=2&test3=a=(/bcdef "some title") and [javascript: protocol](javascript:alert('hello there'))
some@mail.address converted to mailto: and an escaped@mail.address
if loadable

Internal references (h3 header)

this is a reference link with a match somewhere and an attempt where the actual reference has been forgotten

Here's a simple footnote^[1], and here's a longer one^[2]. Footnotes will appear at the bottom later.

Other internal navigation (h4 header)

top header
second header
fifth header

Lists (SETX h2 header)

1. Ordered list items start with a number and a period
   • Unordered list items start with asterisk or dash
   • Sublist nesting
   • is possible
   • by indentating with four spaces
     1. and list types
     2. are interchangeable
     3. and
        2. can
           3. be
              4. nested
                 5. until
                    6. you're
                       8. tired
2. Ordered list item with
   multiple lines
   1. the numbers
   2. of ordered lists
   3. actually don't
   4. matter at all
      12. unless the start number is other than 1
      13. then you'll have an offset

Nested ordered lists cycle through arabic numerals, roman numerals uppercase, roman numerals lowercase, latin alphabet uppercase and latin alphabet lowercase as numeration.

Tables

Blockquotes, code and definition lists

Blockquote
with multiple lines
as seen in many email programs
start with a >

 preformatted text/code can
start with 4 spaces <code>

or being surrounded by
three ` or ~
<!-- html comments are not
rendered as such here -->

Definition list containing

definition lines that

start with a :

Nesting

1. List items can contain

   Blockquotes

2. or
   

   Tables	Column2
   R1C1	R1C2

3. also

   code with
   multiple lines

4. and
   accomplished and
   unaccomplished tasks

Same goes for

blockquotes

1. with
2. nested
   • lists

definition lists

with multiple

lines

Tables nested	within	blockquotes
are	possible	as well

Safety related content that should pose lesser threat with safeMode

<a href="http://some.shady.website">totally legit website link</a>
<a href="javascript:void(0)" onclick="alert('click event')">a with click event</a>
<a href="javascript:alert('a with js href')">a href with click event</a>
[markdown link with js protocol href](javascript:alert('md with js href'))

safeMode restricted tags

e.g. is this input really part of your ui? <input type="text" />
<script>alert('this script injection had been presented by disabled safeMode')</script>

1. This is the first footnote. ↵
2. Here's one with multiple lines and other elements. Indent the content to include it in the current footnote.
   Add as many lines as you like.

   code blocks
   are supported

   as well as

   blockquotes

   with inline code

   and	of
   course	tables

   1. and lists
   2. with the next type though ↵
