Enhancement Request: Add Icelandic HTML Entities to unescapingTable

Description: I would like to request the addition of Icelandic HTML entities to the unescapingTable in the HTML string mappings. Specifically, it would be beneficial to include the following entities:

• Þ for Þ
• þ for þ
• ú for ú
• é for é

Rationale: Icelandic texts often contain these characters, and their inclusion in the unescapingTable would enhance text processing by allowing accurate decoding of HTML-encoded Icelandic strings. This would improve the usability and accuracy of the library when handling Icelandic content.

Proposed Solution: Update the unescapingTable to include the mappings for these Icelandic entities. Here is an example of the proposed additions:

Additional Information: These updates align with the existing functionality of the library and provide better support for Icelandic language text processing.

Thank you for considering this enhancement. I appreciate the effort in maintaining and improving this project.

Kind regards
