#11688: crash in latex export

[Neal Becker]

How do you see latin9?
In lyx the setting Document/settings/language/encoding is 'language default'.

If I try export/LaTeX/luatex or export/LaTeX/pdflatex it crashes.
Haven't tried other varieties.
What other info is needed?  Do I need to supply the figures as well?

 If I open the .lyx file in emacs, the encoding says
U -- utf-8-unix (alias: mule-utf-8-unix cp65001-unix)

UTF-8 (no signature (BOM))
Type: utf-8 (UTF-8: Emacs internal multibyte form)
EOL type: LF
This coding system encodes the following charsets:
  unicode

The bib file says:
U -- utf-8-with-signature-dos

UTF-8 (with signature (BOM))
Type: utf-8 (UTF-8: Emacs internal multibyte form)
EOL type: CRLF
This coding system encodes the following charsets:
  unicode
