Description

The latest QGIS3.0.3 under Mac OS X 10.12.6, freshly installed using "QGIS-macOS-3.0.3-1.dmg" from qgis.org

Right after starting QGIS3 I find the following Processing messages in the Log Messages panel:

2018-05-28T16:37:35 CRITICAL Could not open SAGA algorithm: RiverGridGeneration.txt
ascii' codec can't decode byte 0xc3 in position 75: ordinal not in range(128)

I checked the file mentioned in the (CRITICAL) message:
~/QGIS/python/plugins/processing/algs/saga/description/RiverGridGeneration.txt
It does indeed contain 0xc3 at byte 75 - as the Unicode lead-in for an 'a' with umlaut (diaeresis) mark. There are also 2 other cases later in the file of 0xc3 for 'u' with umlaut.

However, when I edited the file to replace the 2-byte ä and ü with plain ASCII 'a' and 'u', this had no effect on the next QGIS3 startup - same error. Perhaps the "RiverGridGeneration.txt" data is cached somewhere, or the error message is misleading?

Also, upon QGIS startup the CRITICAL message above is followed by a number of WARNING messages:
