Transliterate English text using the Greek alphabet

Transliterate English text using the Greek alphabet is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Rules

A rather silly little task intended as a bit of fun as well as a simple exercise in text substitution. So, if you're a Greek speaker or an expert in ancient Greek, please don't take it too seriously!

As there isn't a one-to-one correspondence between the English and Greek alphabets, we need some rules:

Greek letter	Corresponding English letter(s)
alpha	a
beta	b or v
gamma	g
delta	d
epsilon	e (but not ee)
zeta	z
eta	h or ee (but not ch, kh, ph, rh or th)
theta	th
iota	i or j
kappa	c, k, q or ck (but not ch and kh)
lambda	l
mu	m
nu	n
xi	x
omicron	o (but not oo)
pi	p (but not ph or ps)
rho	r or rh
sigma	s (but not ps)
tau	t (but not th)
upsilon	u or y
phi	f or ph
chi	ch or kh
psi	ps
omega	w or oo

In the case of lower-case sigma, use ς when s is the final letter of an English word or σ otherwise.

Ignore Greek diacritics (accents and breathings) but use the same capitalization, spacing and punctuation as in the English text.

Example

English: The quick brown fox jumped over the lazy dog.

Greek: Θε κυικ βροων φοξ ιυμπεδ οβερ θε λαζυ δογ.

Task

Transliterate the following English text into Greek using the above rules:

I was looking at some rhododendrons in my back garden,
dressed in my khaki shorts, when the telephone rang.

As I answered it, I cheerfully glimpsed that the July sun
caused a fragment of black pine wax to ooze on the velvet quilt
laying in my patio.

If your language does not support the printing of non-ascii characters, then you can instead transliterate the following lower-case pangram:

sphinx of black quartz, judge my vow.

Just represent the Greek letters by their names in angle brackets. For example:

the dog => <theta><epsilon> <delta><omicron><gamma>
