If you read that out loud as if it were Spanish, it would sound like the original French pronunciation for Galois. So, good job! :-)

Russian spelling is mostly phonetic. It tries to keep the idea of spelling that word is a program for sound making machine, which knows nothing about pronunciation of a particular word, just follow simple rules for interpreting letters.

As I understand, Spanish is much like this, it keeps spelling simple. If so, then there are nothing surprising that transliteration from cyrillic into latin make sense from Spanish point of view.
