Apns cuts message with emoji at strange place

[vanquang9387]

Hi everyone,
I had some tests with emoji (numbers from 1 to 10)
1: 1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟
2: 1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟
3: 1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟1⃣2⃣3⃣4⃣5⃣6⃣7⃣8⃣9⃣🔟

But messages were cut out at strange places:

Are there any problems of counting unicode characters with apnsPHP?
