_ (the underscore) is the placeholder for exactly one character.
% (the percent sign) is the placeholder for no, one or more than one character.
%% (two percent signs) is the placeholder for no, one or more than one character, but not for blank space (so that a search ends at word boundaries).

At the beginning and at the end, these placeholders are superfluous.

Work B.1.6

Centiloquium (tr. before 1229)

This translation, which includes Abū Jaʿfar Aḥmad ibn Yūsuf’s commentary, was prepared by an anonymous translator at an unknown date, but no later than 1229, which corresponds to the terminus ante quem of the Vatican MS. Boudet noted that this version shares occasional words and phrases with Hugo Sanctelliensis’s translation (B.1.3) and suggested that it may have been known and used by Hugo, in which case it would date from the first half of the twelfth century (Boudet, ‘Naissance et conception’, 172-173, and ‘The Medieval Latin Versions’, 289-290 and 297-298). The two extant manuscripts are truncated. The Vatican MS preserves v. 6-88 and the Vác MS only has the title (Liber Ptolomei de centum verbis), the preface and fragments of v. 1, 3-4, 24-26 and 28-31.
