Hi Svetlana,

Thanks for the explanation and the examples!  I think I understand better, and it's not as difficult as I first thought. (At least, I hope so...)

I've attached a new version of the functions.  They work fine with my "Twinkle, twinkle..." example.  Hopefully they will work with your file, too.  I couldn't figure out how to get the font running in LilyPond to check it myself :(

Let me know if this does what you want or if you run into any problems.

Best,

David 

Hi, David!

Yeah, this works like I wanted, but there is one problem. The problem is called UTF-8. All is fine if you have latin lyrics and symbols to color from ANSI encoding. Then if you add cyrillic lyrics - the function messes all the letters. If you try to add some cyrillic symbols to color - lilypond crashes.

  I send you your "Twinkle, twinkle" example with cyrillic lirycs. I converted it from ANSI to UTF-8 (without BOM), otherwise it doesn't work with cyrillic letters at all. 

Steps to reproduce:

1) Compile the file I've sent you - you should see normal cyrillic text below the staff (if you have Arial Normal font).

2) Uncomment line with \colorSymbols function call and compile - text will change to strange symbols. As I remember from my PHP expierence this happens when you work with full unicode text and non-unicode functions - function takes just the first byte of symbol codes and not the other.

3) Add some cyrillic letters to function parameters and compile - lilypond crashes :(

I don't know if Scheme is capable of dealing with Unicode easily and if you have any expierience with it, but, please, give it a try. Btw, I've checked your first function. It works with cyrillic letters correctly (just don't forget to convert the files to UTF-8).

Thank you very much,

Svetlana.
