So yesterday at a client location, our support guy called me and said this thing is trimming the characters whenever I save it. It was a ckeditor in our application, so basic troubleshooting was to check the system configuration for that page and the ckeditor configuration.
Checked the system configuration, ckeditor configuration, found nothing.
Out of curiosity, checked the schema for the table in which the data is stored, so one of the idiots took the backup of original table and appended it with the date time on which it was backed up. And created a new table with field data type of varchar with a 255 limit.
This was in UAT server as well as Production server. Changed the field type to text again in UAT. Asked to team to get the same thing done on Production server as well.
