Downloading Historical Data from Finam.ru

I am looking for free historical intraday data (e.g., 30 mins, 1 hour) and I have came up to this website finam.ru, which is in Russian but it can be translated.

The link to download the data is here.

However, after the download is completed I get a txt file (or csv) with this strange message:

¬˚ Á‡ÔÓÒËÎË ‰‡ÌÌ˚ Á‡ ÒÎ˯ÍÓÏ ·Óθ¯ÓÈ ‚ÂÏÂÌÌÓÈ ÔÂËÓ‰.

Has anyone used this source before? Do you know how to actually download the data?

Alternatively, do you know any other source I could use?

Thanks in advance!
