Why do English translations use the name "Eve" rather than "Chava"?

Question

When the Bible is translated into English, most Hebrew names are simply transliterated into Roman characters.

In a few cases though, a completely different name is used.

In the case of Hadassah/Esther, the scripture explicitly gives both names, and thereafter consistently uses one and not the other.

But "חַוָּ֑ה", for instance, isn't transliterated into "Chavah". It is instead given only as "Eve", even in Jewish-sponsored translations of Genesis.

And the man named his wife Eve, because she was the mother of all life.

וַיִּקְרָ֧א הָֽאָדָ֛ם שֵׁם אִשְׁתּ֖וֹ חַוָּה כִּי הִ֥וא הָֽיְתָ֖ה אֵ֥ם כָּל־חָֽי

— Bereishit - Genesis - Chapter 3 (Parshah Bereishit) - Tanakh Online - Torah - Bible

Is there a technical or historical reason why it was done this way?

Answer 1

From here:

"The Septuagint renders חַוָּה as Ζωή (Zo-ay or Zoe -- literally meaning "life" חיּה ). But the name became Ἕυα (Evah or Eve) in other Greek translations. The Tyndale uses Heua, which is related to Eua -- where we get Eve. Eue or Euan in Greek could either be a simple mis-transliteration, or perhaps the Eu- prefix could hint at the Greek meaning "good." The Vulgate uses "Hava". The letter "ח" in Hebrew is often softened to an English "H" by people who cannot pronounce the harsher KH sound with their throat."

The Vulgate was authored by Jerome, one of only two Church Fathers who knew Hebrew, therefore he was able to suggest a transliteration that was much more closer to the original. However, the reason Eve became the more popular version is likely because most people, not knowing Hebrew like Jerome, had difficulty even with his version, necessitating a further softening of the H to an E. From Eva it somehow became Eve.

Answer 2

The standard seems to be set by the fact that the name has a commonly accepted translated version.

Indeed Artscroll writes this explicitly in their "Translation And Commentary" introduction to the Stone chumash. First they point out how they blended Sephardi vowel and Ashkenazi pronunciations resulting in Akeidas Yitzchak and not Akeidat Izhak or Akeidas Yitzchok. Afterwards, at the very end of that introduction they write:

In the translation of the Text, however, we have generally followed the commonly accepted English usage, such as Abraham, Moses, Methuselah, and so on.
