Re: Encoding Issue for .ly Files on CPDL

I have checked this website.
It displays Unicode correctly in web pages.
But it does not display Unicode on text files

These two exemple files contain a accented character

  * Tra me così dicendo (i grave)
  * Copyright © 2026 by CPDL (copyright sign)

If one download the file instead of opening it, the characters are correct.
But not when displayed as text.

It is indeed quite a general problem (not limited to this particular website), due to the 
way text files are displayed in browsers)

I do not know how to correct this at the level or the websiste.

I have tested locally how text files are displayed, ans I have the same result... (using 
Firefox on Linux Ubuntu).

One work-around is to correct the text files by adding the *byte-order mark* (*BOM*) 
<https://en.wikipedia.org/wiki/Byte_order_mark>
(it adds 3 bytes at the beginning of the file which indicates that the file is to be read 
in UTF-8 format (and in which ordre to read the groups of 2 bytes). This is quite easy and 
fast to do if one knows how, and does not affect the use of the file by Lilypond.

Here is a *test page with one of these files 
<https://silvain-dupertuis.org/test/lilypond/displaying-text-files.html>* - the original 
and the one with the BOM added, where one can see that this solves the problem. And it 
seems important to correct the problem, especially when it come to lyrics and any other 
language than English...
