Fix RichTextBox file format is not a problem

RichTextBox file format is incorrect:

Reason: Rich text box LoadFile method only supports RTF file or standard ASCII text This document, our general text document is ANSI or UTF-8 format, so, reported this error.

Workaround: Use Notepad to edit the text, and then save the file as a rich Text format. Then double-click Open RTF file to enter the RTF edit page. Then save as RTF file, note that the encoding format must be Rich Text format.

Graphic:

1. (Because the test machine does not have a right-click New RTF file) first create a new RTF file with Notepad.

2. Open with the RTF editor and Save As.

* Note Save format must be RTF format.

Save it.
