[R] International phonetic symbols in R.

This is a very vague and badly formed question. Also long-winded.
My apologies --- it's the best I can do, currently.

The scenario:
=============

I have (unwisely!) agreed to (try to) give some statistical
help/advice to a graduate student in linguistics.  He has sent me a couple
of Excel (yeeeeeuuuuchhhh!) files --- *.xlsx files --- with some data.

Basically, as I understand it so far, the data consist *essentially* of a
"target sound" and the sound actually produced by a (school-age) child who
is trying to make that sound.  (The sounds are from Mandarin Chinese.)

I can read in the *.xlsx file --- sort of --- using read.xls() from the 
gdata
package.  But the result is useless since the sounds are rendered in 
international
phonetic alphabet symbols.  So it is an incomprehensible mess.

Here is a dput() of the head of a file that I read in:

dput(head(E))
structure(list(Test.items. = c("El at f@nt", "", "Vmb\302\243El@",
"", "t\302\243eIn", "swIN"), Initial. = c("", "", "", "", "",
""), X. = c(NA, NA, NA, NA, NA, NA), Medial. = c("l   ", "f",
"m   ", "l", "", ""), X = c(NA, NA, NA, NA, NA, NA), Final. = c("",
"", "", "", "n", "N"), X.1 = c(NA, NA, NA, NA, NA, NA), Vowel. = c(NA,
NA, NA, NA, NA, NA), I.Cluster = c("", "", "", "", "t\302\243",
"sw"), X.2 = c("", "", "", "", "t at w", "s at w"), M.Cluster. = c("",
"", "b\302\243", "", "", ""), X.3 = c("", "", "b@\302\243", "",
"", ""), F.Cluster. = c("nt", "", "", "", "", ""), X.4 = c("nt\302\254",
"", "", "", "", "")), .Names = c("Test.items.", "Initial.", "X.",
"Medial.", "X", "Final.", "X.1", "Vowel.", "I.Cluster", "X.2",
"M.Cluster.", "X.3", "F.Cluster.", "X.4"), row.names = c(NA,
6L), class = "data.frame")

I have attempted to attach a screen shot of what the *.xlsx file looks like
when I try to "open" it with "LibreOffice Calc".  The attachment is actually
a *.png file, but I renamed it "Screenshot.txt" in the hope that the list
software will not then strip off the attachment.  It is not very 
enlightening
anyway.  Be that as it may, I guess if you want to look at it, save it and
rename it "Screenshot.png" --- given that it comes through at all.  Note 
that
column H (now empty) and column I (after the string "F cluster") initially
contained kids' names.  Same name in the two columns.  (Don't ask *me*!!!) I
stripped out these names lest there be some confidentiality issues.

Ill-posed question:
===================

I am totally flummoxed by this mess.  Can anyone give me any
guidance as to how I might proceed so as to get a data frame with
meaningful column names and visible symbols in the columns, such that
I might be able to, e.g., cross-tabulate the "target" and "actual"
columns?

What do I need to do?  Do I need to install a font (or fonts)? Where
do I get them?  How do I install them?  (I am --- still --- running
Fedora 17.  If I have to upgrade to Fedora 18 to get anywhere, I guess
I will bite the bullet and do so.  Hate to mess with a system that is
working comfortably, but.)

I did an RSiteSearch() on "IPA font" which turned up 5 hits, relating
to plotting functions from the phonTools and phonR packages, but they
might as well have been written in Mandarin for all that I understood
of them.

I would be ever-so-humbly grateful for any advice, guidance, recipes,
assistance, whatever.  If more info is needed, I can *try* to provide
it, but I've told pretty well everything that I know at the present
time.

     cheers,

     Rolf Turner
