+
+This is a mathematical script/calligraphic virtual font based on the URW clone of Zapf Chancery. 
+
+Install the TDS in the usual way. There is no map file to enable. 
+
+The effect of 
+
+\usepackage[scaled=.9]{urwchancal}
+
+is to redefine \mathcal to invoke the appropriate size of urwchancal scaled by the factor .9. The option mathscr instead redefines \mathscr to do the same thing without affecting \mathcal.
+
+The virtual font urwchancal was produced using fontinst from the raw text font uzcmi8r, with adjustments to the font metrics in accordance with my tastes in side-bearings, accent placement and subscript position.

+\begin{document}
+\maketitle
+The URW clone of the universally available PostScript font Zapf Chancery may be used as a math calligraphic font by means of the following lines in the preamble:
+\begin{verbatim}
+\DeclareFontFamily{OT1}{pzc}{}
+\DeclareFontShape{OT1}{pzc}{m}{it}%
+              {<-> s * [1.2] pzcmi7t}{}
+\DeclareMathAlphabet{\mathpzc}{OT1}{pzc}{m}{it}
+\end{verbatim}
+The results are not always good if you attach math accents or sub-/super-scripts, as the following fragment shows. The display below is the result of
+\begin{verbatim}
+\[A^2_k\quad\mathpzc{M}_1\hat{\mathpzc{C}}\mathpzc{\hat{C}}\mathpzc{M}_k^2\]
+\end{verbatim}
+
+
+(Computer Modern (cmmi10) A followed by URW Chancery:)\\
+\[A^2_k\quad\mathpzc{M}_1\hat{\mathpzc{C}}\mathpzc{\hat{C}} \mathpzc{M}_k^2\]
+(The accents are not always where you might expect, letters may inexplicably vanish, and spacing of subscripts and superscripts can be unpredictable.)
+
+This small package provides a virtual math font linked to \verb|uzcmi8r| with side-bearings, subscript position and accent position adjusted manually for each glyph. 
+Following 
+\begin{verbatim}
+\usepackage[scaled=1.15]{urwchancal}
+\end{verbatim}
+ which redefines \verb|\mathcal| to output URW Chancery glyphs, the input line 
+\begin{verbatim}
+\[A=\bar{\mathcal{M}}^2_k+\hat{\mathcal{Z}}.\]
+\end{verbatim}
+yields
+\[A=\bar{\mathcal{M}}^2_k+\hat{\mathcal{Z}}.\]
+In addition to \verb|scaled|, there is on option \verb|mathscr|, which enables \verb|\mathscr| rather than \verb|\mathcal| to point to URW Chancery.
+
+The long tails on some of the glyphs make this font problematic as a math font, but it has some virtues, not the least being its universal availability. For a font of similar appearance without the long-tail problems, consider the script font in Mathematica5.
