Just remember this combination:-Command + control. It is also very simple and easy to use. Using keyboard shortcuts is the fastest method to insert emoji on your text. 1) Using keyboard shortcut.SelectionStart/Length, or. Select All won’t even select all the text anymore!This happened to me, and odds are it’ll happen to you if your app does anything with TextArea and. Find can’t properly select what it’s found. Syntax highlighting no longer highlights the right words. Suddenly, everything goes sideways. One day, a user adds an emoji or two to their text while editing.Dim t as Text = "□□♂️"It looks like Text measures length in extended grapheme clusters (or what most people probably think of as “logical characters”). This emoji is comprised of 5 values: 0x1f926, 0x1f3fc, 0x200, 0x2642, 0xfe0f.Let’s start with the string-like variable types. I’ll use the same example emoji that he does: a man facepalming. A good overview of the issue is this piece by Henri Sivonen. (And bugs.) The fundamental challenge is that there are several legitimate ways to count the length of an emoji. In the case of the sample emoji, that gives a length of 7.If you want to count like NSString, this method works: Sub countLikeNSString(t as Text)Measures of length are also used when calculating string index values. NSString, which is the basis for most of what the Mac does with text, measures length in UTF-16 code units. (If you iterate on t.Codepoints, you’ll get 5 values back.)There’s one other important measuring system used behind the scenes, at least on Mac (I haven’t done any testing on Windows yet). UnicodeMode property that is supposed to determine how they count string length. Now let’s look at how TextAreas count length.As of 2020r1, TextAreas have a. For example: dim index as IntegerThat’s fun. ![]() SelectionLength will be 7.StyledText also seems to use the NSString counting system.Select All will not actually select all if there are emoji in the text area. Select the sample emoji, and. SelectionLength all return values consistent with how NSString counts. Our example emoji from above takes 5 codepoints, and the number of bytes varies depending on how codepoints are being encoded.CharacterPosition. A simple smiley face emoji (0x1f600) may take up two bytes, but that’s really only one codepoint. Which is… fine? But it doesn’t match the documentation.StyledText offset values appear to be consistent with how Text.Length measures text. SelectionLength will be 5. Select the sample emoji, and. SelectionLength are returning values consistent with how String.Length measures text. I think this is a bug (61659).SelectionStart and. That breaks down when the TextArea is using a different counting system from String and Text.If you use Codepoints mode, you will need to explicitly convert String- and Text-based lengths and offsets to NSString-based values.Hopefully UnicodeMode is going through some birthing pains and these issues get resolved. If the sample emoji is selected, neither are true.This is a major issue because a lot of code operating on TextAreas will grab TextArea.Value, stuff it in a String/Text variable, search the variable for various things, and then try to apply the resulting String/Text-based offset values back to the TextArea via. This impedence mismatch leads to offset issues.For example, I think most people would expect one or more of the following to be true: TextArea.SelectionLength = TextArea.SelectedText.Length()TextArea.SelectionLength = TextArea.SelectedText.ToText().Length()If the selection is plain ASCII text, both are true. I expect most people are using this mode, largely because it’s the legacy mode (well, Native is the legacy mode, but on Mac that is the same as Codepoints).The main problem I have with Codepoints is that its NSString-based counting system doesn’t line up with either String or Text’s counting system. Best vm resolution for macI think I lean towards alignment, but I’m concerned that might introduce hidden and unavoidable O(N*N) conversions from one counting system to another. Alignment with how either String or Text counts, to avoid impedence mismatches.Performance and alignment may involve tradeoffs. Performance, which probably means aligning with how the native OS counts text. A mode should use the same counting system everywhere.
