I have this problem with a mod im developing where I have a norwegian translation thing for the mod however, when I recompile it errors on the lines with norwegian characters such as 'ø' take this for example:

 

        public static int redCedarPlanksID;
public static Block redCedarPlanks;

public MedievalBlocks()
{
	this.redCedarPlanks = (new BlockMedieval(redCedarPlanksID, 0, Material.wood)).setHardness(2.0F).setResistance(5.0F).setStepSound(Block.soundWoodFootstep).setBlockName("medievalCedarPlanks").setRequiresSelfNotify();			
	RegisterBlocks(new Block[]
			{
			redCedarPlanks
			});

	this.namesNorwegian("nb_NO");
}

        public void namesNorwegian(String lang)
{
	LanguageRegistry.instance().addNameForObject(redCedarPlanks, lang, "Røde Sederplanker");
        }

private void RegisterBlocks(Block ablock []) 
{
	Block ablock1[] = ablock;
	int i = ablock1.length;
	for(int j = 0; j < i; j++)
	{
		Block block = ablock1[j];
		GameRegistry.registerBlock(block);
	}	
}

 

I get this error when recompiling:

Go here: http://www.fileformat.info/info/charset/UTF-8/list.htm

 

Look up for the character which throws an error, then look in the second row which looks like this: LATIN CAPITAL LETTER O WITH STROKE (U+00D8)

Take the code in the brackets (after the U+; here 00D8) and replace the character with this: \u00D8 - The code you have comes after the \u

ok Thank you!
