While creating Item all types of special characters should be allowed [closed]

Question

While creating Item all types of special characters should be allowed. I tried to alter the regular expression in sitecore.config but unable to resolve it

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

Answer 1

If you would like to allow all chars in items names in Sitecore you could use this patch:

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <settings>    
      <setting name="ItemNameValidation">
        <patch:attribute name="value">^.*$</patch:attribute>
      </setting>
   </settings>
  </sitecore>
</configuration>

Regex explanation:

^ asserts position at start of the string
.* matches any character (except for line terminators)
* Quantifier — Matches between zero and unlimited times, as many times as possible, giving back as needed (greedy)
$ asserts position at the end of the string, or before the line terminator right at the end of the string (if any)
