Styled text with message entities

Telegram supports styled text using message entities.

A client that wants to send styled messages would simply have to integrate a Markdown/HTML parser, and generate an array of message entities by iterating through the parsed tags.

Special care must be taken to consider the UTF-8 length of strings when generating message entities, see example implementations: tdlib, MadelineProto.

Nested entities are supported.
For example the following HTML/Markdown aliases for message entities can be used:

• messageEntityBold => <b>bold</b>, <strong>bold</strong>, **bold**
• messageEntityItalic => <i>italic</i>, <em>italic</em> *italic*
• messageEntityCode => <code>code</code>, `code`
• messageEntityStrike => <s>strike</s>, <strike>strike</strike>, <del>strike</del>, ~~strike~~
• messageEntityUnderline => <u>underline</u>
• messageEntityPre => <pre language="c++">code</pre>,

```c++
code
```

The following entities can also be used to mention users:

• inputMessageEntityMentionName => Mention a user
• messageEntityMention => @botfather (this mention is generated automatically server-side for @usernames in messages)

A number of other entities are also available, see the type page for the full list ».
