Description

The usage of nonbasic Latin alphabet and special characters in Sitecore Forms might result in the removal of those characters. The issue occurs after saving changes. It affects label field of the List item section and the Field name of the Details section in FormsBuilder.

You can also view these changes in field names under form items in the Content Editor.

Solution

The creation of the label and the Field name is controlled by the ItemNameValidation and InvalidItemNameChars settings.

To resolve the issue, consider one of the following options:

• Upgrade Sitecore XP instance to Sitecore XP 10.3.0 or later.
• For Sitecore XP 10.2, download and install the pre-release as specified in KB1001439.
• For Sitecore XP 10.1, download and install the pre-release as specified in KB1001300.
• Alternatively, change the regular expressions in the following settings to allow the required characters that are stripped when saving a form.
  
  1. From

     <setting name="InvalidItemNameChars" value="\/:?"<>|[]" />

     to

     <setting name="InvalidItemNameChars" value="" />

  2. From

     <setting name="ItemNameValidation" value="^[\w\*\$][\w\s\-\$]*(\(\d{1,}\)){0,1}$" />

     to

     <setting name="ItemNameValidation" value="." />

     Note that you can use the value above, although in this case all characters in item names are allowed when creating or renaming items in Sitecore.
  
  Note: The setting must be patched by creating a configuration patch file in the \App_Config\Include\zzz folder.
