The TeX primitives commands 0136 <code>\uppercase</code> and <code>\lowercase</code> only work for American 0137 characters. The LaTeX commands <code>\MakeUppercase</code> and 0138 <code>\MakeLowercase</code> commands also change characters accessed by 0139 commands such as <code>\ae</code> or <code>\aa</code>. The commands 0140 <code>\MakeUppercase</code> and <code>\MakeLowercase</code> are robust but they have 0141 moving arguments (see <a href="_005cprotect.html#g_t_005cprotect">\protect</a>). 0142 </p> 0143 <p>These commands do not change the case of letters used in the name of a 0144 command within <var>text</var>. But they do change the case of every other 0145 Latin letter inside the argument <var>text</var>. Thus, 0146 <code>\MakeUppercase{Let $y=f(x)$</code>} produces ‘<samp>LET Y=F(X)</samp>’. Another 0147 example is that the name of an environment will be changed, so that 0148 <code>\MakeUppercase{\begin{tabular} ... \end{tabular}}</code> will 0149 produce an error because the first half is changed to 0150 <code>\begin{TABULAR}</code>. 0151 </p> 0152 <p>LaTeX uses the same fixed table for changing case throughout a 0153 document, The table used is designed for the font encoding T1; this 0154 works well with the standard TeX fonts for all Latin alphabets but 0155 will cause problems when using other alphabets. 0156 </p> 0157 <p>To change the case of text that results from a macro inside <var>text</var> 0158 you need to do expansion. Here the <code>\Schoolname</code> produces 0159 ‘<samp>COLLEGE OF MATHEMATICS</samp>’. 0160 </p> 0161 <div class="example"> 0162 <pre class="example">\newcommand{\schoolname}{College of Mathematics} 0163 \newcommand{\Schoolname}{\expandafter\MakeUppercase 0164 <!-- /@w -->\expandafter{\schoolname}} 0165 </pre></div> 0166 0167 <a name="index-package_002c-textcase"></a> 0168 <a name="index-textcase-package"></a> 0169 0170 <p>The <samp>textcase</samp> package brings some of the missing feature of the 0171 standard LaTeX commands <code>\MakeUppercase</code> and 0172 <code>\MakeLowerCase</code>. 0173 </p> 0174 <a name="index-package_002c-mfirstuc"></a> 0175 <a name="index-mfirstuc-package"></a> 0176 0177 <p>To uppercase only the first letter of words, you can use the package 0178 <samp>mfirstuc</samp>. 0179 </p> 0180 0181 0182 0183 <hr/><div class='referenceinfo'> <a href='https://latexref.xyz/'> <i>Unofficial LaTeX2e reference manual</i></a></div> 0184 </body> 0185 </html>
