euro sign in hook not handled correctly

I created a hook that displays the shipping costs. This hook incudes some text with a euro sign (€) in it. It seems the euro sign prevents the whole block from being rendered.

I added the text via a hook in the product data and all the product information block (main-content) was not loaded. Also added the text via a hook in the cart content and the complete cart content block was not loaded.

When I added the text directly in product_data.tpl the product information loaded just fine including the euro sign.

did you use an html entity code for the symbol or are you trying to use your keyboard value? Try using:

I used the keyboard (ALT 0128) to produce the euro sign. € works better. Thx
