I would like to bring up another discussion about the spelling of a couple names on the wiki. The current spellings for these 2 pages are "Salemburg" and "Cobert".
The kata for Salemburg/Selmburg is セルムブルグ (Serumuburugu), where "ru" is likely an approximation for "l" and extra "u"s are there due to too many consonants following one another. In other words, this kata name would imply Selmburg, not Salemburg, which would likely be written as セイレムブルグ (Seiremuburugu), if we take that the "a" should be pronounced as "ei".
For Cobert/Corbatz, the dub has reached episode 9 and it pronounces his name as Corbatz or something... not sure about the spelling of course.
The only thing wrong with your kata is that Japanese tend to omit the "r" sound and instead just extend the previous vowel, so it's コーバッツ. Anyway, the dub is semi-official (as in, it has made mistakes, but they should be more reliable than fan translations), so I guess Corbatz makes more sense than Cobert.
