UConverter::transcode() always emits an E_WARNING when an invalid encoding is specified

[KidFlo]

From manual page: https://php.net/uconverter.transcode

---

The documentation should mention that passing an invalid/unsupported encoding name to this method will result in an E_WARNING being emitted (and no error code defined), regardless of the values set for intl.use_exceptions or intl.error_level.

This seems more like a bug in the intl extension than a documentation issue. So transferring to php/php-src.

@Girgias with the following

<?php
UConverter::transcode("\x0a", 'nein!!', 'UTF-8');
UConverter::transcode("\x0a", 'UTF-16BE', 'da!');
?>

I get the E_WARNING

Warning: UConverter::transcode(): Error setting encoding: 4 - U_FILE_ACCESS_ERROR in /home/dcarlier/test-intl.php on line 2

Warning: UConverter::transcode(): Error setting encoding: 4 - U_FILE_ACCESS_ERROR in /home/dcarlier/test-intl.php on line 3

is there a missing case ?

[Girgias]

The issue is that it always emits a warning instead of being silenced/promoted to exception depending on the intl error setting as far as I understand.

Ah thanks. will have a look soon-ish.
