+, LyX determines the encoding of a portion of text from the language of

+ If the document contains text in more than one language you may get more

+LyX also supports Unicode output, which is particularly useful if you need
+ lots of special symbols or non-alphabetic scripts, respectively.
+ If you want to use this (and your LaTeX installation supports Unicode,
+ for that matter), choose one of the four utf8 variants from the list below.
+ Unfortunately the unicode support of standard LaTeX is quite incomplete,
+ so it is not uncommon that a file with lots of unicode symbols works fine
+ with
+\family sans
+use language's default encoding
+\family default
+ (when LyX uses it's list of known LaTeX-commands), but does not work with
+ a fixed utf8 encoding (when the list of known LaTeX-commands is ot used,
+ because all unicode symbols can be encoded in utf8).
