Encoding: changed from 'Language Default' to Other: 'Unicode (utf8)'

Very good. I don't understand why lyx still defaults to a mix of
incompatible 8-bit encodings for mixed language documents!


Language package: 'Custom:' the input field left empty
At the end of the Preamble I added:
\usepackage[greek,english]{babel}
make sure that the main Language english comes second after greek!

This is not required. Instead, I recommend to leave the language at its
default (babel with 8-bit TeX, polyglossia with Xe/LuaTeX).

You can always set the language of parts of the document via

   Edittext-stylecustomlanguage

(or similar, my LyX speaks German). This will also add the second (third,
...) language to the document preamble.


Usage example:
to replace the English character 'a' type:  \textgreek{a}  in an ERT box.

I recommend to input Greek Unicode characters. The Latin transcription has
the disadvantage of not working in PDF bookmarks and side-bar toc.

If you don't want this, write just a (or logos or whatever), mark it, and
set it to language Greek.
With 8-bit TeX (pdflatex, o.ä.), this will convert the text into Greek
script using the Latin transcription provided by the LGR font encoding.
(Side-effekt: you cannot easily have Latin words/characters inside Greek
text with 8-bit TeX! Wrap it in \textlatin or set the language accordingly
to German, French, Swedisch or whatever it is.)

(Actually, \textgreek is just doing this as well, but setting the language
is more LyXisch than ERT and also fixes hyphenation, spell-checking etc.)

(Also, LyX will wrap Greek Unicode characters in \textgreek for the
font/script change if required.)


This works equally well for words (I have not tried sentences yet).

This works for sentences too. See the documentation of the greek-fontenc and
babel-greek packages.


The extra tidbit of this great transliteration is that the Greek
characters are printed upright! and NOT slanted!

This is not due to the transliteration, but to the fact that you use text
fonts not math fonts. It is the same effect with Latin letters in text mode
vs. a math box.

This works also with the Greek Unicode input (even if you set the latex
encoding from utf8 to ASCII).

If you have difficulties with Unicode input, there is also the textalpha
and alphabeta package (both are part of greek-fontenc). With

   \usepackage{textalpha}
   
you can input Greek symbols by name, e.g. as \texalpha ... \textOmega

(in LyX as ERT).

With

   \usepackage{alphabeta}
   
you can drop the text prefix: input Greek symbols as

\alpha ... \Omega (in LyX as ERT) and, according to their position in text
or an equation, the mathematical or text fonts will be used.


B) as A) but in glosses
In place of  'a'  type  \textgreek{a}  again but this time just like
ordinary standard text, e. i. NOT inside an ERT box (in fact, one cannot
add ERT boxes in a gloss and I had an evil grin in my face when doing as
told by Jürgen.)

You may try with Unicode characters here, but I am not sure whether the
glossary package is 8-bit save. Otherwise, I would use
\textalpha over \textgreek{a}

Hallo Günter,
thanks for all of your comments and additional input.

After going through lots of experimenting and teachings I can subscribe 
to all of your points but one: In Glosses the only way to get Greek 
parts is using the Transliteration Method.
For all who are interested I recommend to read Chapter 7. Using 
covington (glosses and examples) in a beamer presentation of 
http://wiki.lyx.org/LyX/LinguistLyX
It was edited and updated to the current version by Jürgen Spitzmüller 
as a respons to my so many nagging questions on the issue.


Jürgen emphasizes:
So-called verbatim context (such as TeX mode, verbatim paragraphs, 
linguistic glosses or program listings) does not allow language changes

limitation), so you cannot insert Greek (unicode) glyphs to verbatim 
context (if you do you get lots of LaTeX errors).

Thanks to you and all who were interested and answered my questions. 
Only one is left unanswered:

How do I get a roof (triangle) in trees using the forest package?

This is IMO a false conclusion: The LICR (latex internal macro
representation) should work in these cases, too.

For Greek, this means that the abovementionend alphabeta and textalpha
packages should allow the use of \alpha or \textalpha in glosses etc..

Morning Günter,

I have no doubt that both \usepackage{textalpha} and 
\usepackage{alphabeta} do work as you said (certain settings provided).
However, with my current settings they definitely do not, neither in 
ordinary text nor in glosses.

See screenshot attached.

So, as a layman and tangled up in transforming my son's linguistic 
papers from 'word' to Lyx I feel this discussion may be something for 
experts. But if you tell me which settings should be used I am always 
eager to try again.
Meanwhile I am happy to have all my problems left behind in following 
what is outlined in http://wiki.lyx.org/LyX/LinguistLyX Chapter 7. 
"Using covington (glosses and examples) in a beamer presentation"


Thanks and Cheers!
Michael

Very good. I don't understand why lyx still defaults to a mix of
incompatible 8-bit encodings for mixed language documents!

 Language package: 'Custom:' the input field left empty

 At the end of the Preamble I added:
 \usepackage[greek,english]{babel}
 make sure that the main Language english comes second after greek!

This is not required. Instead, I recommend to leave the language at its
default (babel with 8-bit TeX, polyglossia with Xe/LuaTeX).

You can always set the language of parts of the document via

  Edittext-stylecustomlanguage 

(or similar, my LyX speaks German). This will also add the second (third,
...) language to the document preamble.

 Usage example:
 to replace the English character 'a' type:  \textgreek{a}  in an ERT box.

I recommend to input Greek Unicode characters. The Latin transcription has
the disadvantage of not working in PDF bookmarks and side-bar toc.

If you don't want this, write just a (or logos or whatever), mark it, and
set it to language Greek. 
With 8-bit TeX (pdflatex, o.ä.), this will convert the text into Greek
script using the Latin transcription provided by the LGR font encoding.
(Side-effekt: you cannot easily have Latin words/characters inside Greek
text with 8-bit TeX! Wrap it in \textlatin or set the language accordingly
to German, French, Swedisch or whatever it is.)

(Actually, \textgreek is just doing this as well, but setting the language
is more LyXisch than ERT and also fixes hyphenation, spell-checking etc.)

(Also, LyX will wrap Greek Unicode characters in \textgreek for the
font/script change if required.)

 This works equally well for words (I have not tried sentences yet).

This works for sentences too. See the documentation of the greek-fontenc and
babel-greek packages.

 The extra tidbit of this great transliteration is that the Greek 
 characters are printed upright! and NOT slanted!

This is not due to the transliteration, but to the fact that you use text
fonts not math fonts. It is the same effect with Latin letters in text mode
vs. a math box.

This works also with the Greek Unicode input (even if you set the latex
encoding from utf8 to ASCII).

If you have difficulties with Unicode input, there is also the textalpha
and alphabeta package (both are part of greek-fontenc). With 

  \usepackage{textalpha}
  
you can input Greek symbols by name, e.g. as \texalpha ... \textOmega
(in LyX as ERT).

With 

  \usepackage{alphabeta}
  
you can drop the text prefix: input Greek symbols as
\alpha ... \Omega (in LyX as ERT) and, according to their position in text
or an equation, the mathematical or text fonts will be used.

 B) as A) but in glosses
 In place of  'a'  type  \textgreek{a}  again but this time just like 
 ordinary standard text, e. i. NOT inside an ERT box (in fact, one cannot 
 add ERT boxes in a gloss and I had an evil grin in my face when doing as 
 told by Jürgen.)

You may try with Unicode characters here, but I am not sure whether the
glossary package is 8-bit save. Otherwise, I would use
\textalpha over \textgreek{a}

As a workaround, you can use \mathrm{} in math mode to make the 
characters upright. This is a hack, but if I understand your plight 
correctly, it should produce the desired output.


Well, this would work for a few isolated Greek letters, but the spacing 
is different, particularly between words, and line lengths can be 
messy.  I real Greek solution would be best.  Unfortunately, I can't 
help with making that work.

Single upright Greek characters need to be inserted here and there.
Many hours spent on experiments and attempts to use Greek characters

I have a beamer with Greek text, here and there.  I will post this to
