[Tex/LaTex] Unicode greek letter or new greek letter

greeksymbolsunicode

I need chi letter as the one to the right:

My issue is that when I either use $\chi$ or \textgreek{q} I don't get what I wish to. I would also be happy with U+03C7 unicode character, but I
don't want to use XeTeX but LaTeX instead. I've read this post but I couldn't solve my problem with this…

That's the chi in the Symbol Adobe font.

\documentclass{article}
\usepackage{mathptmx}
\usepackage{amsmath}

\newcommand{\upchi}{\text{\usefont{U}{psy}{m}{n}\symbol{'143}}}

\begin{document}

X\upchi

$\upchi+X_{\upchi}$

\end{document}

[Tex/LaTex] Biber writes incorrect unicode encoding of \’\i

Use the correct syntax:

Author = {Ver{\'{o}}nica Mac{\'{i}}as}

Or directly

Author = {Verónica Macías}

ensuring that the file is UTF-8 encoded. Works both in pdflatex and xelatex. The \i after the main accents is not required in LaTeX since several years, but the braces around the accented letters is BibTeX syntax from the origins.

If it's really not possible to modify the documents, the following hacks seem to work

XeLaTeX:

\begingroup\lccode`\~=\string"0131
  \lowercase{\endgroup\protected\def~}#1{\char\string"00ED}
\catcode\string"0131=\active

or, more simply,

\catcode`ı=13 \protected\defı#1{í}

PdfLaTeX:

\DeclareUnicodeCharacter{0131}{í}
\DeclareUnicodeCharacter{0301}{}

More complicated things will be needed if you have also \`\i somewhere.

[Tex/LaTex] Insert unicode symbol

You should separate input and output. If you want to print a symbol you at first need a font which contains it. If you want to use normal latex (it will work with xelatex too) you can e.g. use the dingbat font to get an anchor. If you want to use the symbol in the input you must declare it (I'm not sure if the ⚓ copy& paste correctly):

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\DeclareUnicodeCharacter{2693}{\anchor}
\usepackage{dingbat}
\begin{document}
\anchor ⚓ 
\end{document}

With xetex you can use e.g. dejavu sans (if you get the wrong glyph:make sure that you have only version of dejavu sans). Here too you can use commands/other notation if you don't want to use the symbol in the input:

\documentclass[12pt]{article}
\usepackage{fontspec}
\begin{document}
{\fontspec{DejaVu Sans Condensed} ^^^^2693 \char"2693 ⚓}
\end{document}
