postman could not handle unicode characters in url for routing - unicode

Question

I have defined an API Resource in WSO2 ESB like this with GET method:
/sms/{username}/{password}/{src}/{destination}/{body}
Now if I invoke my API through a standard browser like chrome or firefox it works fine and I get response code ok 200
127.x.x.x:8280/sms/username/password/123123123/456456456/سلام
But I can not invoke this API through Postman and it returns Not-Found 404. If I replace 'سلام' with a standard ascii string like 'hello' it works fine and it returns code ok 200:
127.x.x.x:8280/sms/username/password/123123123/456456456/hello
I tried numerous Content-Types in Headers tab of postman including this but it didn't work:
text/html; charset=UTF-8
I also monitored network requests with fiddler. Standard browser send request with this parameters:
Connection: keep-alive Upgrade-Insecure-Requests: 1 User-Agent:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML,
like Gecko) Chrome/70.0.3538.77 Safari/537.36 Accept:
text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,/;q=0.8
Accept-Encoding: gzip, deflate Accept-Language: en-US,en;q=0.9
And Postman send request with this parameters:
Content-Type: text/html; charset=UTF-8 cache-control: no-cache
Postman-Token: 5ccc574f-54d2-4c5b-ac72-b0f5f5a8e0be User-Agent:
PostmanRuntime/7.3.0 Accept: /
accept-encoding: gzip, deflate Connection: keep-alive
I use postman v6.4.4

Answer 1

You need to manually encode parts of the URL.

Answer 2

I tried this issue with WSO2 ESB 5.0.0. It works for me as you expected through postman.
<api xmlns="http://ws.apache.org/ns/synapse" name="test-api" context="/test">
<resource methods="GET" uri-template="/value/{val1}">
<inSequence>
<log level="full">
<property name="test" expression="get-property('uri.var.val1')"/>
</log>
<payloadFactory media-type="json">
<format>{ "test": "$1"}</format>
<args>
<arg evaluator="xml" expression="get-property('uri.var.val1')"/>
</args>
</payloadFactory>
<respond/>
</inSequence>
<outSequence>
<send/>
</outSequence>
</resource>
</api>
Request: http://localhost:8280/test/value/سلام
Response:
{
"test": "سلام"
}
Try with WSO2 ESB 5.0.0.
