Outlook Message Format vs Unicode: Decoding the Differences

Understanding the nuances between Outlook message format vs Unicode is essential for anyone who regularly communicates via email. When we dive into the world of Microsoft Outlook, we encounter a choice that can significantly affect how recipients compose and read our messages: whether to use Outlook’s default message format or switch to Unicode. This decision impacts text display and compatibility across different email clients.


The traditional Outlook message format, known as ANSI, has limitations in character set and language support. In contrast, Unicode offers a much broader range of characters, encompassing virtually every written language. This makes it invaluable for global communication, where diverse alphabets and symbols are used. Selecting Unicode over ANSI ensures that our emails maintain their intended content without encountering issues such as improperly displayed characters.

By adopting a Unicode format in Outlook, we’re choosing a more inclusive approach that caters to international correspondence. It’s crucial for businesses with global reach and individuals who communicate beyond English-speaking borders. In this discussion, we’ll explore the strengths and considerations of each option, helping you make an informed decision about your Outlook email settings.

What is Outlook Message Format?

When we dive into the world of email communication, especially through Microsoft Outlook, we encounter various message formats. Understanding the Outlook message format is essential for anyone who relies on email for personal or business communication. This format determines how messages are composed, stored, and transmitted to recipients.

Outlook primarily uses two types of message formats: Plain Text and HTML. Plain Text is the most basic form; it doesn’t support any kind of formatting like bold or italics. On the other hand, HTML, which stands for HyperText Markup Language, allows for rich text formatting with different fonts, colors, images, and other multimedia content.

  • Plain Text
  • HTML

Another aspect to consider within these formats is whether they use Unicode or not. Unicode is a character encoding standard that includes a wide range of characters from various writing systems around the world. When an Outlook message format supports Unicode:

  • It can handle languages beyond just English.
  • Special characters and symbols are accurately represented.
  • The potential for cross-platform compatibility increases.

For example, if you’re sending an email in Mandarin using HTML format with Unicode enabled, all the intricate Chinese characters will appear correctly to your recipient regardless of their operating system or email client.

In contrast to non-Unicode formats, which might restrict certain languages or special characters, resulting in garbled text upon receipt—this isn’t something we’d want when conveying important information! Consideration of whether to use Unicode with your chosen Outlook message format should be guided by your audience’s needs as well as their technical capabilities.

What is Unicode?

Unicode is a computing industry standard designed to consistently represent and handle text expressed in most of the world’s writing systems. It has revolutionized the way we manage and display characters across different platforms, programs, and devices. With Unicode, every letter, digit, or symbol from each language has a unique code point—a specific number assigned to it. This ensures that text remains consistent and intelligible regardless of where it’s viewed.

Let’s delve into how Unicode operates in the context of Outlook message format. When you compose an email in Outlook, you want your message to look the same on your recipient’s screen as it does on yours. That’s where Unicode comes into play—Outlook uses this universal encoding standard to maintain the integrity of your messages across diverse systems and software versions.

Here are some fascinating facts about Unicode:

  • As of 2021, Unicode contains over 143,000 characters, covering 154 modern and historic scripts.
  • Emoji also fall under the purview of Unicode—they’re treated like any other character.
  • Before its adoption, computer users faced what was called ‘The ASCII Betrayal’ where characters would often not display correctly on different machines.

Using Outlook with its message format set to Unicode means embracing inclusivity for all languages. No longer are non-Latin alphabets such as Cyrillic or Chinese relegated to question marks or box symbols due to incompatible encoding; they’re displayed crisply as intended.

Embracing a global mindset requires tools that support seamless communication across borders—and that’s precisely what Outlook’s use of Unicode offers. Users can confidently send emails in Japanese kanji one minute and switch over to Arabic script the next—all while knowing their content will be preserved accurately during transmission and reception.

Key Differences between Outlook Message Format vs  Unicode

Understanding the distinction between Outlook message format and Unicode is essential for anyone working with email communication. Let’s dive into their primary differences.

Outlook message formats, such as ANSI (American National Standards Institute) and MSG, are proprietary to Microsoft. They’re designed specifically for storing Microsoft Outlook items like emails, appointments, contacts, tasks, and journal entries on your computer. On the other hand, Unicode is a universal character encoding standard that assigns a unique number to every character in most of the world’s writing systems. This makes it possible to represent and manipulate text consistently across different platforms and programs.

  • File Compatibility: Outlook’s native MSG format works seamlessly within the Microsoft ecosystem but may face compatibility issues with non-Microsoft applications or operating systems. Conversely, Unicode text can be used universally across diverse software environments without trouble.
  • Text Representation: When you’re using an Outlook message format that isn’t based on Unicode, characters from languages outside of Western European scripts might not display correctly. But with Unicode support in newer versions of Outlook (.ost and .pst files), you’ll find that it supports a wide range of characters, including those from Asian alphabets to emojis.

The volume of characters supported by each system shows another stark contrast:

Character Support Outlook Message Format (Non-Unicode) Unicode
Number Limited (typically up to 256) Extensive (over 143,000)

Moreover, when considering data exchange among various users globally:

  • Global Communication: For businesses operating internationally or individuals communicating across borders, relying on a system without full Unicode support can lead to miscommunication when special characters are involved. Emails sent through older versions of Outlook without proper encoding may arrive at their destination with jumbled content instead of coherent messages.

In essence:

  • The proprietary nature vs global standardization
  • File compatibility concerns vs universal accessibility
  • Text representation limitations vs inclusive character depiction

There are some fundamental distinctions we must keep in mind while deciding which one suits our needs best when dealing with digital communication platforms like email clients. Whether sharing important documents or just saying hello in another language—using a format compatible with Unicode ensures everyone gets the right message.
