HashtagParser

An IMfmParser implementation for detecting "hashtag" syntax. Strings starting with "#" will be search results.

The content cannot be left empty.
The content cannot contain half-width spaces, full-width spaces, newlines, or tab characters.
The content cannot include . , ! ? ' " # : / 【】 <> 【】 ( ) 「」（）.
Parentheses can only be included in the content when they come in pairs. Relevant pairs: () [] 「」（）.
Recognize as a hashtag if the character before # does not match case-insensitive.
If the content is only numbers, it will not be recognized as a hashtag.
