Question

Is there a way to determine if the input data contains single-byte characters?

Answer

Please specify as follows in Match to Regular Expression logic and Assign Variables.

.*[[0-9][a-z][A-Z][ｱ-ﾝ][ -/:-@\[-\`\{-\~]]+.*

note 
The setting above includes single-byte Japanese characters. Please adjust the setting by your requirement.

The logic returns [true] if single-byte characters are included, and returns [false] if not.

For available regular expression patterns, please refer to the following page.
