According to the Korean Regulation of loanword orthography, 'Zara' is spelled as '자라'. However I was not able to find the same spelling as your name with 'h' in between. I believe you can also spell your name as '자라' in Korean even if there is a 'h' in it. *Here is the link for the source. http://kornorms.korean.go.kr/example/exampleList.do?regltn_code=0003 * Hope it helps and please follow me at koreanclass.canada on Instagram!

This link might be helpful, it's the currently used transcription: https://en.wikipedia.org/wiki/Revised_Romanization_of_Korean

Zahra would be "자흐라"

Z -->> ㅈ / ㅉ : maybe 자라/자아라 or 짜라/짜아라 or 잘아/자알아, etc (cause 'h' in the name just lengthens 'a', and, i think, is barely pronounced) ^^^
