Using the Font Overview
In the Font Overview window there is a list of categories and a grid where all cells have a caption and a part that shows the glyph.
The categories panel is a convenient way to quickly show a subset of characters or glyphs and allows you to display them in several groupings and orderings. To change the current grouping and ordering use the Overview Toolbar on the main toolbar.
When creating Unicode fonts, the categories panel shows a convenient list of all Unicode blocks that contain at least one mapped glyph. When you add new characters through the Add Characters dialog or change character mappings the Unicode categories are automatically updated. If you are creating a symbol font, a symbol category will be shown instead.
The Glyphs category contains several subcategories. One of them is the Unused category, which is only shown when the font contains one or more glyphs that are inaccessible by normal means. It is recommended to delete such glyphs as they are of no use.
Each cell has a caption that is used to display the glyph name, Unicode name, the code-points or the glyph index. To select the kind of caption, use the Overview Toolbar or right-click in the Font Overview window and select a specific caption. Setting the caption type to Automatic will automatically change the captions to the value of the current selected grouping method. This means that when you group by Advance Width, the cell captions display the Advance Width value.
You can also switch between decimal and hexadecimal values for the code-points and glyph indexes in the Display Format submenu of the View menu.
