the WriteApi does not check whether a tag value cotains unauthorized characters ("\n","\r"...)

まだ誰も着手していません。

InfluxDB has some restrictions on tag values : they cannot contain some characters such as: line feed (\n), carriage return (\r). Currently, the Java client library does not check whether values of tags are safe (free of unauthorized characters) before writing them into InfluxDB.
For example, I have a measurement classe called `Temperature`, and it contains a tag field `location`. When I put `location="mad\nrid"` and I write it using `WriteApi`, it will throw the following exception: `partial write: unable to parse 'temperature,location=mad': missing fields dropped=0`. So a partial write will be done in the influxDB database: a new measurement `rid` will be mistakenly created, and it will contain only a part of the write.
If a tag value contains '\r', the java client will not even throw an exception, and it will perform an incorrect write into the database.

I think it would be really useful to add a method that ensures that tag values are correct before sending them to InfluxDB through the line protocol, in order to avoid incorrect writes and anomalous behaviors.

まず、タグ値をInfluxDB line protocolにシリアライズするWriteApiのパスを追跡します。改行と復帰を含む値がどのように処理されるかを確認し、安全でない値によって部分的または不正な書き込みが発生しないようにバリデーションを追加します。既存のWriteApiテストがあれば、それを使って両方の文字をカバーします。
