I suspect commas are an important delimiter/escape-character in the way keyword-data is stored in googles data-centers, so that there is no hope this will ever change.
1) Are these omitted commas sufficiently rearranged in the search-evaluation algorithms? I doubt so, because in my account those keywords don't seem to perform as well as they are supposed to.
2) What is the recommended way to cope with this? Substitution by the utf-8-sequence "%2c" did not work either?
