Template:Chset-color-letter-box/doc

Usage
Used with Template:chset-tableformat data rows to indicate a color for character code cells classified as letters (L*) by Unicode. Note that Unicode categories do not differentiate between alphabetic, syllabic and logographic characters, they are all classified as "letter"s for their role in writing.

This alternative is a boxed variant of Template:chset-color-alpha in order to indicate some other information in addition to the type: for example, a derivation from a base codepage, or a codepoint for which multiple definitions exist in some sources.

The default color of the box is gray, but can be changed by providing an optional parameter specifying the color.

For as long as there is no need to differentiate one or a few of the cells in a group from the other cells in the same group, use Template:chset-color-letter instead.
