The font of a custom symbol changes when the symbol is inserted onto the
drawing.
Solution
To retain the same font that the symbol text was created with:
1. In the Menu, select 'Insert-->Symbol-->Custom'.
2. In the Setting group of the Custom Symbols dialog, toggle
'Annotation Preferences' to 'Use Definition'.
3. Place the symbol.
This will use the annotation preferences that the symbol was defined with,
instead of the current annotation preferences of the drawing.
