Great question!

When emphasis is shown for a single letter, simply place the typeform symbol indicator before the affected letter. Do not use a terminator.

The effect of the typeform symbol indicator, whether transcriber-generated or not, extends only to the next letter or symbol.

In <i>Braille Formats,</i> see Example 20-27. Although the letters are bold, the method is the same. See UEB 9.5.1 for an example that uses a transcriber-defined typeform symbol indicator.

A few reminders:

1. A transcriber-defined font follows the same rules as the established fonts: italics, bold, underline, and script.
2. It is a special symbol and must be explained.
3. If you assign a transcriber-defined indicator to represent blue in the current volume, that indicator can only represent blue throughout the complete transcription.
