userMetadata value exception: Unexpected char 0x5546 at 0 in x-amz-meta-tag value: 商品

// sample code
MinioClient minioClient = MinioClient.builder().endpoint("https://play.min.io").credentials("Q3AM3UQ867SPQQA43P2F", "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG").build();
ByteArrayInputStream bais = new ByteArrayInputStream(“abcd”);
Map<String, String> userMetadata = new HashMap<>();
userMetadata.put("tag", "商品");
ObjectWriteResponse objectWriteResponse = minioClient.putObject(
PutObjectArgs.builder().bucket("zhangsan").object("my-objectname").stream(
bais, bais.available(), -1)
.userMetadata(userMetadata)
.build());

the method .userMetadata(userMetadata) call requestBuilder.header(entry.getKey(), entry.getValue()); , okhttp check header name and value ascii, but my userMetadata value contains chineses words , okhttp Headers.Builder.addUnsafeNonAscii only check name ascii;
@line

minio-java/api/src/main/java/io/minio/MinioClient.java

Line 470 in e529717

requestBuilder.header(entry.getKey(), entry.getValue());

,
Replacing Request.Builder.header(String name, String value) with okhttp Headers.Builder.addUnsafeNonAscii and Request.Builder.headers(Headers headers) may solve my problem .

Hope to understand my poor English expression .
