[TextMeshPro]Whitespace character “u200B” is added to the text property when a TMP_Text component is assigned as the text component property on a TMP_InputField
How to reproduce:
1. Open the user’s attached “TMPCharacter.zip” project
2. Enter Play Mode
3. Observe the “Input Text String” log in the Console window
Expected result: “Length: 0, WhiteSpace: True” is logged
Actual result: “Length: 1, WhiteSpace: False” is logged
Reproducible with: 3.0.6 (2021.3.32f1), 4.0.0-pre.2 (2022.3.13f1, 2023.1.20f1, 2023.2.0f1, 2023.3.0a14)
Reproduced on: macOS 13.5.2 (Intel)
Not reproducible on: No other environment tested
Notes:
- not reproducible when the TMP_Text component is assigned as the InputField component property on a TMP_InputField
- false is returned when logging “char.IsWhiteSpace”
- text is not properly trimmed from the string when using “string.Trim”

Resolution Note:
Hi, the unicode standard considers the zero width space (U+200B) to be a formatting mark rather than a space or whitespace character. This is why the method IsNullOrWhiteSpace returns false. This character is used in the core of text selecting and editing so it needs to stay in the InputField for TextMeshPro. We are however removing the need for this character in our future Text backend (ATG).
