1. frac 1 2 or x 2 instead of x 2 although some users frown on this prac tice A simplistic version of the makefirstuc command is newcommand FirstUC 1 MakeUppercase 1 Here FirstUC abc is equivalent to MakeUppercase abc and since MakeUppercase requires an argument it grabs the first token the character a in this case and uses that as the argument so that the result is Abc The glossaries package needs to take into account the fact that the text may be contained in the argument ofa formatting command suchas acronymfont so makefirstuc has to be more complicated than the trivial FirstUC shown above but at its basic level makefirstuc uses this same method and is the reason why in most cases you don t need to enclose the first character in braces So if MakeUppercase stuff works then makefirstuc stuff should also work and so should makefirstuc foo stuff but if MakeUppercase stuff doesn t work then neither will makefirstuc stuff nor makefirstuc foo stuff Try the following document documentclass article usepackage utf8 inputenc usepackage T1 fontenc begin document MakeUppercase bc end document This will result in the error Argument of UTFviii two octets has an extra This is why makefirstuc a amp bc won t work It will only work if the character Ais placed inside a group The reason for this error message is due to TE2. color red text you need to define say red as color red and use red text Examples e makefirstuc abc produces Abc e makefirstuc emph abc produces Abc MakeUppercase has been applied to the letter a rather than emph Note however that makefirstuc em abc produces ABC first objectis em abc so this is equivalent to MakeUppercase em abc and makefirstuc em abc produces abc em doesn t have an argument therefore first object is em and so is equivalent to MakeUppercase em abc e makefirstuc a bc produces Abc e makefirstuc ae bc produces Abc e makefirstuc ae bc produces bc e makefirstuc amp bc produces Abc Note that non Latin or accented characters appearing at the start of the text must be placed in a group even if you are using the inputenc package The reason for this restriction is detailed in Section 4 In version 1 02 of mfirstuc a bug fix resulted in a change in output if the first object is a control sequence followed by an empty group Prior to version 1 02 makefirstuc ae bc produced Bc However as from version 1 02 it now produces Abc xmakefirstuc emakefirstuc glsmakefirstuc Note also that newcommand abc abc makefirstuc abc produces ABC This is because the first object in the argument of makef irstuc is abc so it does MakeUppercase abc Whereas newcommand abc abc expandafter makefirstuc ex

5. X having been written before Unicode was invented Although amp may look like a single character in your text editor from TgxX s point of view it s two tokens So MakeUppercase Abc tries to apply MakeUppercase to just the first octet of 4 This means that the second octet has been separated from the first octet which is the cause of the error In this case the argument isn t a single token so the two tokens the first and second octet of 4 must be grouped MakeUppercase A bc Note that XqIpX and therefore XqHTRXx is a modern implementation of TEX designed to work with Unicode and therefore doesn t suffer from this drawback Now let s look at the XBIEX equivalent of the above example documentclass article usepackage fontspec begin document MakeUppercase bc end document This works correctly when compiled with XqETpx This means that makef irstuc abc will work provided you use Xq4TpX and the fontspec package
