Set Parameter: Validation.json
## Overview
Pleasanter counts all characters as one character, regardless of whether they are half-width or full-width characters. If you want to use this to count half-width characters as 1 character and double-width characters as 2 characters, set this parameter. The settings will be reflected in the counting method of "[Manage Table: Editor: Column Advanced Settings: Maximum Number of Characters](/en/manual/table-management-maxlength)".
## Notes
* In principle, no changes are necessary. Set this only if you want to change the counting method.
* When changing parameters, please refer to "[Confirmation When Changing Parameters](/en/manual/parameter-edit)".
