may help you . It's indeed the UTF-8 encoding 11000010 10100000 of NBSP \xA0. As said earlier, this works: code :
= preg_replace('/<p>\p{Z}*<\/p>/u', '<p class="notmobile"> </p>', $f);

I wish this help you By default the PHP regex engine considers your string as a suit of bytes (i.e. as a suit of one byte characters). When you use the u modifier, the regex engine changes two things: code :
(*UTF8)(*UCP)yourpattern

I wish this helpful for you You should not use photo capture like this. According to documentation - extras.get("data") contains small preview and should not be used for other purposes then showing preview. You should use camera the other way. There is a Kotlin sample from my library. It creates file in DCIM dir and pass to Camera it's URI to use as output: code :
private fun takePhoto() {
val photoIntent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
val dirDCIM = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)
val storageDir = File(dirDCIM, "/${config.cameraFolderName}/")
if (!storageDir.exists()) storageDir.mkdirs()
currentCameraImageFile = File(storageDir, "photo_${UUID.randomUUID()}.jpg")
val uri =
FileProvider.getUriForFile(this, "$packageName.fileprovider", currentCameraImageFile!!)
photoIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri)
val resolvedIntentActivities =
packageManager.queryIntentActivities(photoIntent, PackageManager.MATCH_DEFAULT_ONLY)
for (resolvedIntentInfo in resolvedIntentActivities) {
val packageName = resolvedIntentInfo.activityInfo.packageName
grantUriPermission(
packageName,
uri,
Intent.FLAG_GRANT_WRITE_URI_PERMISSION or Intent.FLAG_GRANT_READ_URI_PERMISSION
)
}
startActivityForResult(photoIntent, PHOTO_REQUEST_CODE)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
when (requestCode) {
PHOTO_REQUEST_CODE -> {
val photoFile = currentCameraImageFile ?: return
if (resultCode == Activity.RESULT_OK && photoFile.exists()) {
// Do your stuff
} else {
// If result is not successful - delete temporary photo file
photoFile.delete()
}
currentCameraImageFile = null
}
}
}
<provider
android:name="android.support.v4.content.FileProvider"
