Non-latin symbols in links in the whitelist break the bot

[mymedia2]

The bot is frozen when it tries to send the full whitelist of links if this list contains links with non-latin characters

Steps to reproduce:

• Add the bot to a supergroup
• Send the next command /whitelist пример.рф
• Try to get the list of white links via simply /whitelist command
• The bot is frozen and doesn't answer anymore

The bot version is 4.2.0 rev.b41a10f

Wait, is this a DoS on the whole bot?

@NotAFile the "the bot is frozen and doesn't answer anymore" part was fixed with this commit and was caused because the API was returning a "message text must be encoded in utf-8" error while sending the list

Well, then this can be closed I guess.

But the other problem is still there (/whitelist not working with non-latin characters)
