I’m trying to import from a Vanilla forum using the instructions posted here. However, I get the following error when I run the vanilla.rb import script:

Traceback (most recent call last):

I’ve tried changing the MySQL database character set to UTF8 following the instructions here and then re-exporting the porter file, but that didn’t resolve the issue. Any suggestions?
You can google stuff about UTF-8 encoding. You need to do something that will coerce the table into UTF-8. The time that I did it, there were further complications because some rows were in one format and others in another format. I think that I did some nonsense where I coerced things on a value-by-value basis.
Oh. It’s aweful. You best bet, based on a vague recollection of a single time I did this over a year ago, is to play around with as many different conversions as you can until you can finally hit on one that works for all or most data. I think that I did a bunch of one-by-one transformations that ended up being a waste of time when I stumbled on some conversion that worked for all (most?) data.
Here is what I did. Use at your own risk. (This was vbulletin, FWIW).
def char_map(raw_original)
raw = raw_original.dup
debug = false # (raw.length > 50)
# windows 1252
all = ''
win_encoded = ''
### WIN1252 encoding
win_encoded = ''
begin
win_encoded = raw.force_encoding('utf-8').encode("Windows-1252",
invalid: :replace, undef: :replace, replace: ""
).force_encoding('utf-8').scrub
rescue => e
puts "\n#{'-'*50}\nWin1252 failed for \n\n#{raw}\n\n"
win_encoded = ''
end
### ISO 8859 encoding
iso_encoded = ''
if all.length == 0 && win_encoded.length > 0 && win_encoded != raw
all = (debug ? "Win1252--" : '') + win_encoded
else
all = raw
end
all = old_char_map(all)
all
end
私も数ヶ月前に(開発者ではありませんが )このプロセスを経験し、セルフホストのVanillaフォーラムからセルフホストのDiscourseへの移行を成功させることができました。私にとって重要だったのは、Vanilla Porterでデータエクスポートを行う際に、最初のドロップダウンメニューで「Vanilla 2」を Source Forum Type として選択することでした。
