However, the parsing error is harmless as the workaround is already "the
right thing". Just try:
1. Take a *.lyx file and in a text editor change, e.g.
\inputencoding auto
to
\inputencoding unsupported-encoding
2. open the file in LyX
I get the message
BufferParams.cpp (3218): Unknown inputenc value `unsupported-encoding'.
Using `auto' instead.
in the terminal and the document opens just fine and compiles without
problems.
Furthermore, LyX documents with "\inputencoding pt254" are a very rare case
(maybe even nonexisting):
* Due to missing "iconv" support, there are no documents with this setting
generated by tex2lyx.
The minimal example
\documentclass{article}
\usepackage[pt254]{inputenc}
\begin{document} Test me. \end{document}
compiles with pdflatex without problem, but tex2lyx fails with
#> tex2lyx pt254.tex
Creating file /tmp/pt254.lyx
Error 22 returned from iconv_open(in_cd_): Das Argument ist ungültig
terminate called after throwing an instance of
'lyx::iconv_codecvt_facet_exception'
what(): iconv problem in iconv_codecvt_facet initialization
Abgebrochen
(in the times when LyX did not use iconv but tables in lib/encodings, the
encoding pt254 was not yet supported).
* As documents with setting "\inputencoding pt254" fail to export to/with
(8-bit) LaTeX (other exports ignore the setting), it is very unlikely
someone will have set this encoding "by hand" and kept it so.
For eventually existing rare cases, it is very hard to guess what would be a
"sensible value":
* someone setting inputencoding away from "auto" to an
Cyrillic-Asian-Mac 8-bit encoding may not be served well with any
auto-guessed replacement.
In any case, I don't think it is worth the effort.
