It was my fault, I have various files, they were formatted differently: part UTF-8 (the glossary) and part ISO-8859.. (checked with the 'file' command) Now I 'recode'(d) all to UTF-8, edited the \inputenc command to UTF-8 and now it works everything (except for the .bib file)


You can use \hat in a math environment: \documentclass[]{article} \begin{document} \begin{equation} \vec{r}_1=r_1\hat{r}_1=-r_1\hat{e}_r \end{equation} \end{document}


The key for \label and \ref consists of ASCII letters, digits, and punctuation (LaTeX Companion, 2ed). Package babel does some hacking to allow its shorthands. The key is internally used to create a command \r@<key> via \csname. This can be broken by anything, which is not a character or does not expand to a letter. Accented letters quite often ...


hehe, ohh, Steve and Mico. What a delight to be in your company. Dear user89, you have to think thin. \thinspace my dear, \thinspace. \documentclass{article} \usepackage{mathtools} % for "\mathclap" macro \usepackage{amsfonts} \usepackage{amssymb} \usepackage{accents} \renewcommand{\vec}[1]{\ensuremath{\mathbf{#1}}} ...


I am guessing the shift is due to an italic correction that might otherwise be expected in math mode. But in this case, the overletter is not italic. Thus, a simple stack will center the underscript. This first MWE shows the before and after: \documentclass{article} \usepackage{mathtools} % for "\mathclap" macro \usepackage{amsfonts} ...


If you don't want the underline to extend that far over the symbols' “boundaries”, you might want to consider using the accents package for the macro \underaccent{<accent>}{<glyph>}. See the following MWE for an illustration: \documentclass{article} \usepackage{accents} \begin{document} $\underaccent{\bar}{Y}$ vs.\ $\underline{Y}$ ...


I would start with \underline{Y} in either inline-math or displaystyle-math mode.


For automatic correct positioning, you should define a new math alphabet: \documentclass{article} \usepackage{amsmath} \usepackage{amssymb} \DeclareMathAlphabet{\mathbcal}{OMS}{cmsy}{b}{n} \begin{document} \begin{align*} \check{A}\\ \check{\mathbf{A}}\\ \check{\mathcal{A}}\\ \check{\mathbcal{A}} \end{align*} \end{document}


The font table shows all of the glyphs present in the font. For LaTeX to typeset a character in a certain font, it must either be supported directly by the font e.g. the character is @ and the font contains an @ symbol. Or, it must be possible to construct the character from characters the font does supply e.g. the character is ŵ and there's no ŵ in the ...


First of all, you absolutely need to tell whoever is in charge of the project what you’re almost saying in the comments: what you’re asking to do here is the consequence of bad decisions that you shouldn’t have to deal with. All you’re doing here is working around these bad decisions because you can’t tackle the main issue. Now, as long as you’re aware of ...
