Problem:
- Issue 1 (solved): The Swedish letters ÅÄÖ/åäö do not print out correctly when used with
listingspackage. - Issue 2: How can it be solved so that the Swedish letters also get orange color like the rest of the letters?
- Issue 3: How can it be solved to get the PHP-line (line 10) to be on the same line as line 9?

The errors indicate issues with the Swedish letters. I used literate for the listings package to solve this issue but without success.
Current outcome:
Desired outcome:
The letter ä to be the same color as the rest (i.e. orange) and the PHP-code to be on the same line as the <p> element.

Using a Unicode-aware engine
If changing engine to either XeTeX or LuaTeX is an option, then you can remove the
literatestuff from the\lstset, removeinputencand addfontspec. With those modifications it just works.Note that in the code below I set
belowskipandaboveskipto0ptwhere necessary to remove the gap between the differentlistings, rather than using\vspace{-12pt}.Using
pdflatexWhile the following works with
pdflatexit is limited. This is taken more or less directly from section 9 of thelistingsmanual. Theliteratestuff is again removed, and two lines are added to\lstset:The comments with the Scandinavian characters are typed between
`and'.escapeinsidemeans that between the two characters specified,listingsjumps back to 'normal' LaTeX mode. Theescapebeginline means that the\colorspecification will be added to the start of each escaped part, and because LaTeX renders this as usual, the text is coloured.You see where the limitation lies -- as used here all such text blocks will have the same colour. If you only have such characters in comments, then it's no problem. If you have them elsewhere, you will have to add an extra
\color{..}at the start of every escaped sequence that should have a different colour, as with\color{editorOrange}in this case. Hence it means a lot of extra fiddling.(Note that I am by no means an expert when it comes to
listings, so there may well be better ways of doing this.)
