Steps to Reproduce

1. Attempt to display Greek text with emojis in Flutter
2. The following string causes the issue:

   stanera σας προσφέρει μια διαμονή ηρεμίας, αποσύνδεσης και χαλάρωσης 🧿💆
   

Expected results

The text should display correctly without any replacement characters.

Actual results

Flutter shows the following error:

flutter: ║                  stanera σας προσφέρει μια διαμονή ηρεμίας, αποσύνδεσης και χαλάρωσης 🧿💆�

With the error message:

Bad UTF-8 encoding (U+FFFD; REPLACEMENT CHARACTER) found while decoding string

Additional Information

The source bytes were:

[102, 108, 117, 116, 116, 101, 114, 58, 32, 226, 149, 145, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 32, 115, 116, 97, 110, 101, 114, 97, 32, 207, 131, 206, 177, 207, 130, 32, 207, 128, 207, 129, 206, 191, 207, 131, 207, 134, 206, 173, 207, 129, 206, 181, 206, 185, 32, 206, 188, 206, 185, 206, 177, 32, 206, 180, 206, 185, 206, 177, 206, 188, 206, 191, 206, 189, 206, 174, 32, 206, 183, 207, 129, 206, 181, 206, 188, 206, 175, 206, 177, 207, 130, 44, 32, 206, 177, 207, 128, 206, 191, 207, 131, 207, 141, 206, 189, 206, 180, 206, 181, 207, 131, 206, 183, 207, 130, 32, 206, 186, 206, 177, 206, 185, 32, 207, 135, 206, 177, 206, 187, 206, 172, 207, 129, 207, 137, 207, 131, 206, 183, 207, 130, 32, 240, 159, 167, 191, 240, 159, 146, 134, 239, 191, 189]

The issue appears at the end where bytes [239, 191, 189] represent the UTF-8 replacement character (U+FFFD), suggesting the original data was corrupted or truncated during encoding/decoding.

Flutter doctor

Please run flutter doctor -v and paste the output here.

Additional context

This appears to be related to handling Greek text combined with emojis, where the string gets truncated or corrupted, resulting in an invalid UTF-8 sequence at the end.
