I have CiviCRM 5.13 on Drupal7 with clickatell release v4.1. Clickatell integration works, SMS can be sent via HTTPS from the browser. Database and environment is set to UTF-8.
However, if an SMS is compiled in CiviCRM, non-English characters, like é,á,... are lost or transformed in the SMS body. If the same text is sent over curl / HTTPS directly to Clickatell, there is no such issue.
I suspect this unicode issue arises from the clickatell extension. It uses the utf8_decode() function here to decode the message text from a UTF-8 string to ISO-8859-1 before posting to Clickatell. Hence Clickatell manages UTF-8 messages, the use of utf8_decode() is not necessary, and removing it resolves my issue above.
