ligaturespdftexwinedt
Is there anyway to find and remove ligatures from tex file? Sometimes when I copy/paste a text to Winedt, it shows perfect, but when I compile it to Pdf, some issues appear, e.g. finding becomes nding.
I am wondering if there is any way to search and find these characters?
Here is an example file (needs utf8 encoding).
\documentclass{article}
\begin{document}
fi
\end{document}
Your option 3 is using
U+0069 (LATIN SMALL LETTER I) U+0304 (COMBINING MACRON)
instead of
U+012B (LATIN SMALL LETTER I WITH MACRON)
You get the former when inputting the latter by using
\usepackage{newunicodechar}
\newunicodechar{ī}{ī} % use "i + combining macron" in the second argument
or, without too much hassle in inputting strange characters,
\newunicodechar{ī}{i\char\string"0304 }
This is the output from your test file (omitting option 2).
Minimal example:
\documentclass[12pt, a4paper]{scrbook}
\usepackage{fontspec}
\setmainfont[Ligatures=TeX]{Brill}
\usepackage{newunicodechar}
\newunicodechar{ī}{i\char\string"0304 }
\begin{document}
\begin{verbatim}
1a. Kitāb an-Naǧāt fī l-ḥikma.
1b. \emph{Kitāb an-Naǧāt fī l-ḥikma}.
3a. Kitāb an-Naǧāt fī l-ḥikma.
3b. \emph{Kitāb an-Naǧāt fī l-ḥikma}.
\end{verbatim}
1a. Kitāb an-Naǧāt fī l-ḥikma.
1b. \emph{Kitāb an-Naǧāt fī l-ḥikma}.
3a. Kitāb an-Naǧāt fī l-ḥikma.
3b. \emph{Kitāb an-Naǧāt fī l-ḥikma}.
\end{document}
Because it it too long for an comment this answer. I'll try to show you the reason for your errors.
Try to compile the follwing MWE:
\documentclass{article}
\usepackage{lmodern} % Latin Modern
\usepackage[T1]{fontenc} % Font encription
%\usepackage[utf8]{inputenc} % input encription utf-8
\usepackage[latin1]{inputenc} % input encription Latin1
\begin{document}
Test to test encoding (this is written in utf-8): äöüß ÄÖÜ
\end{document}
You should get errors. Now delete the % sign (line utf-8) and comment the following line (latin1). Compile. Now you should have no errors.
The reason is that file and encoding information are not the same. They have to be the same.
With WinEdt you can store a file as utf-8 with file-- Save as and set file-type to :UTF-8.
If this MWE runs for you try to copy some lines from your tex file into the MWE and try to compile it. Try to save it as utf-8. Hope this helps you.
Update:
I just installed WinEDT and found TeX in the bottom line. Click on TeX and you will get a window like this:
Now click on CP Converter and you can see the encription code WinEDT found and you can change it.

This is commonly due to bad font information, but is solvable. The ligatures that can give problems are
fffiflffiffl, if a modern font is used.You can solve at once your problem with
The relevant code is between the two
%%prefixed lines. Just keep it at hand and paste it when needed.A “search and replace” can be better, for the production version of the document.
