Microsoft Word 2007 and RichEdit 6.0 introduced the native Office math facility. PowerPoint, Excel, and OneNote followed suit in 2010, and Mac Word followed in 2011. But ironically the native math facility didn’t have a recognizable name. “Microsoft Equation Editor” (MEE) seemed natural, but that's the name of the Design Science math ...

A few years ago, I visited two very interesting countries, Vietnam and South Korea. Being actively involved in writing software (mostly RichEdit) for editing the world’s scripts, I was naturally fascinated to see Vietnamese and Korean text displayed in profusion. The Vietnamese and Korean scripts were designed with a common purpose in mind: ...

The new Windows 11 Notepad uses RichEdit and runs on up-to-date Windows 11 installations. In addition to a Windows 11 look with rounded corners and a dark-theme option, the new Notepad includes several standard RichEdit editing enhancements, such as Alt+x for entering Unicode characters, Ctrl+} for toggling between matching brackets/...

Do you know that Unicode includes the fraction characters ↉ ½ ⅓ ¼ ⅕ ⅙ ⅐ ⅛ ⅑ ⅒ ⅔ ⅖ ¾ ⅗ ⅜ ⅘ ⅚ ⅞? Well thanks to existing character standards, ½ ⅓ ¼ ⅕ ⅙ ⅛ ⅔ ⅖ ¾ ⅗ ⅜ ⅘ ⅚ ⅞ were added in Unicode 1.1 in 1993, and ↉ ⅐ ⅑ ⅒ were added in Unicode 5.2 in 2009. Programs like Microsoft Word ...

In slide presentations and elsewhere, it can be handy to have math text color and math background color. In fact, Presentation MathML has the attributes “mathcolor” and “mathbackground”. This post describes the operators Noah Doersing added to his UnicodeMathML implementation to enter text and background color using UnicodeMath. I ...

RichEdit Stories

Word and RichEdit have stories, but you won’t find their story’s definition in a dictionary. Their story is an object that stores rich text in computer memory. Rich text consists of Unicode plain text, associated character and paragraph formatting, and embedded objects such as images. Such a story can contain the narrative of a traditional...

RichEdit Place Holder

Sometimes you need a text box that cues the user to type something in, such as, “Start a conversation”. As soon as the user types something, the cue text vanishes, and the user sees what the user typed. If the user deletes all the text, the cue text reappears. Such a text box is called a place-holder control. The Microsoft 365 RichEdit has...

For many years, I’ve wanted to use real mathematical notation in computer programs for code that is mathematical in nature. The document UnicodeMath discusses this in some detail in Section 6. Using UnicodeMath in Programming Languages. Over the years, some advances beyond ASCII (invented in the 1960’s!) have been made. For example, you ...
