The character-grouping pattern followed by Pullum and Ladusaw in their <#167#>Guide<#167#> was adopted as the basis for the <#1519#> WSUIPA<#1519#> font layout. The characters are grouped together according to shape rather than usage. Therefore, the ``a'' shapes occupy the first positions: '00 through '04, ``b'' shapes are in positions '05 through '11 and so forth. The accents and diacritics follow the character shapes and are in the last positions in the font. This approach was taken because under it was assumed that under most circumstances, the user would most likely be accessing the characters with the use of macros rather than by typing large portions of entirely phonetic text. Aside from keeping like shapes together, the positioning of the <#1520#> WSUIPA<#1520#> font was fairly arbitrary.
