It is first necessary to fetch the paragraph properties of the paragraph that contains the character. The pap.istd of the fetched properties specifies which style sheet entry provides the default character properties for the character. The character properties recorded in the style sheet for that style are copied into a local CHP. Then, the piece containing the character is located in the piece table (plcfpcd) and the fc of the character is calculated. Using the character's FC, the page number of the CHPX FKP that describes the character is found by searching the bin table (hplcfbteChpx). The CHPX FKP stored in that page is fetched and then the rgfc in the FKP is searched to locate the bounds of the run of exception text that encompasses the character. The CHPX for that run is then located within the FKP, and the CHPX is applied to the contents of the local CHP. The process thus far has created a CHP that describes what the character properties of the character were at the last full save. Now apply any character sprms that were linked to the piece that contains the character. If pcd.prm.fComplex is 0, pcd.prm contains 1 sprm which should be applied to the local CHP if it is a character sprm. If pcd.prm.fComplex is 1, pcd.prm.igrpprl is the index of a grpprl in the CLX. If that grpprl contains any character sprms, apply them to the local CHP. After applying all of the sprms for the piece, the local CHP contains the correct properties for the character.
Characters that are within the same piece, same paragraph, and same run of exception text are guaranteed to have the same properties. This fact can be used to construct a scanner that can return the limit CPs and properties of a sequence of characters that all have the same properties.
