+- I found a handful of AGROVOC subjects that use a non-breaking space (0x00a0) instead of a regular space, which makes for a pretty confusing debugging...
+- I will replace these in the database immediately to save myself the headache later:
+
+```
+dspace=# SELECT count(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id = 57 AND text_value ~ '.+\u00a0.+';
+ count 
+-------
+    84
+(1 row)
+```
+
+- Perhaps my `agrovoc-lookup.py` script could notify if it finds these because they potentially give false negatives
