Citation relations should be able to handle strange DOIs.

I queried dblp for "Breitenbücher".

Following entry came out:

@InProceedings{Hahn2018b,
  author    = {Michael Hahn and Uwe Breitenb{\"{u}}cher and Frank Leymann and Vladimir Yussupov},
  booktitle = {On the Move to Meaningful Internet Systems. {OTM} 2018 Conferences - Confederated International Conferences: CoopIS, C{\&}TC, and {ODBASE} 2018, Valletta, Malta, October 22-26, 2018, Proceedings, Part {II}},
  date      = {2018},
  title     = {Transparent Execution of Data Transformations in Data-Aware Service Choreographies},
  doi       = {10.1007/978-3-030-02671-4\_7},
  editor    = {Herv{\'{e}} Panetto and Christophe Debruyne and Henderik A. Proper and Claudio Agostino Ardagna and Dumitru Roman and Robert Meersman},
  pages     = {117--137},
  publisher = {Springer},
  series    = {Lecture Notes in Computer Science},
  url       = {https://doi.org/10.1007/978-3-030-02671-4_7},
  volume    = {11230},
  bibsource = {dblp computer science bibliography, https://dblp.org},
  biburl    = {https://dblp.org/rec/conf/otm/0002BLY18.bib},
  owner     = {koppor11},
}

Thus, I have the DOI 10.1007/978-3-030-02671-4\_7

When activating "Citation Relations", I get

Illegal character in path at index 76: https://api.semanticscholar.org/graph/v1/paper/DOI:10.1007/978-3-030-02671-4\_7/references?fields=title,authors,year,citationCount,referenceCount&limit=1000
Error while fetching citing Articles
java.lang.IllegalArgumentException: Illegal character in path at index 76: https://api.semanticscholar.org/graph/v1/paper/DOI:10.1007/978-3-030-02671-4\_7/citations?fields=title,authors,year,citationCount,referenceCount&limit=1000

I think, this needs to be fixed at the DOI parsing logic (or at semantic scholar?)

---

This issue is more about code reading and code understanding. The fix itself is probably 3 lines of code and 10 lines of test case.

Can I work on this issue?

@AbdAlRahmanGad Sure.
