LyX ⇒ Beamer doesn't compile because of inputenc

[tygrysuav]

Recently beamer presentations have stopped compiling if they are not in English. But I need them in Polish and here is the problem. Articles work normally in both languages.

Nothing I found on the web is working. Neither changing the preamble nor setting the LyX itself. I also tried to change the coding in the external program.

I get this message:

Package inputenc Error: Invalid UTF-8 byte 179.
\DeclareFontEncoding{PD1}{}{}

The document does not appear to be in UTF-8 encoding.
Try adding \UseRawInputEncoding as the first line of the file
or specify an encoding such as \usepackage [latin1]{inputenc}
in the document preamble.
Alternatively, save the file in UTF-8 using your editor or another tool

I can not use old files or create new ones. I know it's about UTF-8, but I can not deal with it and I really, really need help.

Below is the code of the sample .lyx file

Code: Select all

\documentclass[polish]{beamer}
\usepackage[T1]{fontenc}
\usepackage[latin2]{inputenc}
\setcounter{secnumdepth}{3}
\setcounter{tocdepth}{3}

Hi,

welcome to the forum!

Why do you use latin2 encoding? It works completely fine for me with utf8:

\usepackage[utf8]{inputenc}

And how to disable latin2 in LyX? Because this line is what LyX adds.

[Stefan Kottwitz]

In the menu go to Document -> Language and change the Coding from default to Others and check what is available.

In Document->Settings->Language I've changed coding to utf8. Now I get this errors:

LaTeX Error: Missing \begin{document}
Undefined control sequence.

Other options also do not work.

[Stefan Kottwitz]

Perhaps post the .log file here, as attachment to a post. The "Attachments" link is below the text edit field, when writing a post.

I added the log file. This version had the language option set to "utf8"

[Stefan Kottwitz]

Strange, as the code works for me fine with utf8. If there's not something different in your actual code than already shown here, it could be an error in a package (pd21enc.def?) of your TeX installation. It seems to be up to date though. Just perhaps, maybe you could try TeX Live instead of MiKTeX.

The last time I compiled the beamer presentation a few months ago. Then everything worked. I do not understand what has changed since then, apart from the updates of LyX, MiKTeX and Windows 10.

Can this package pd21enc.def be reinstalled?

[tygrysuav]

I have uninstalled MiKTeX and installed TeXLive 2018. The problem has disappeared. Case closed.
