How to Filter by Alphanumeric Character Width in Salesforce Reports for Multi-Byte Locale Users

While Salesforce reports can filter by specific text, they cannot distinguish between single-byte and double-byte characters in multi-byte environments like Japanese. To extract records based on specific character widths, a temporary change to the user's locale settings is required.

While report filter can determine whether a specific string has been entered, they cannot create general search conditions such as whether the characters entered in a field are half-width or full-width.

Therefore, it is not possible to set a search condition in a report that checks whether half-width alphanumeric characters have been entered in a specific text field.

Also, even if the search condition is for a specific string (e.g., text field equals "ABC"), as described in the knowledge article, if the logged-in user's Locale is set to "Japanese (Japan)" (a multi-byte environment), both records with the half-width value "ABC" and the full-width value "ＡＢＣ" will be displayed in the report.
