Hello.
Housed on my website video content, I began to add at site map. All the necessary cells filled. And when i uploading site in internet, the file sitemap.xml, produces an error (see add files) to edit it, I can not imagine how. Сode is displayed in the encoding Baltic 1252. Why?
Already on my site 26 videos and I plan to add another large quantity, and therefore it is advisable for me, that my video indexed. What to do? I attach two screenshots (error, and the code itself). Thank you very much.
