It is a Telegram bot API bug?

Question

Working with the bots API.

When I try to use /sendmessage function:

https://core.telegram.org/bots/api#sendmessage

if the text var contains " H" (blank space + H), the message is not sent. Is a bug?

For example, messages with text similar to this not sent: "My name is Julia Hi" or "I am testing HTML tags msg"

https://api.telegram.org/**botAPI**/sendmessage?chat_id=**XXXXXX**&parse_mode=HTML&text=**My name is Julia Hi**

$path = "https://api.telegram.org/YOURBOTAPI";

file_get_contents($path."/sendmessage?chat_id=".$A_CHATID."&text=My name is Julia Hi");

Answer 1

I think is a Telegram API BUG, however I solved it encoding the text param as sugested @Barmar

$text = urlencode('My name is Julia Hi')
$path = "https://api.telegram.org/YOURBOTAPI";
file_get_contents($path."/sendmessage?chat_id=".$A_CHATID."&text=".$text);
