Hello everyone

Use this block:
You will get true if the mark you entered is in the text you entered (and if the mark is not found you will get: false)

It is works for only one special character in one time

You can attach some of these with: or

1. specify all the special characters in a list (take a look what characters are not allowed in firebase)
2. make a list of all those characters
3. set text to “get list” or “is in list”
4. set piece to the label / textbox which needs to get checked.

I prefer to use Regex(Regular Expression) for stuff like this: [Screenshot_20200609-152942_Chrome] Just lowercase - pattern = [^a-z] lowercase Uppercase and space character - pattern = [^a-zA-Z ] Thanks @wangsk789!

Just lowercase - pattern = [^a-z]
lowercase Uppercase and space character - pattern = [^a-zA-Z ]

Lowercase, Uppercase, Numbers 0-9 - pattern = [^a-zA-Z0-9]
