IMO, over-complicated approach. If you know that Russian text (or
Cyrillic in general) always will be in UTF-8 encoding then you only need
fontent with T2A option (but be aware that T2A fits Ok only for Russian)
and inputenc with utf8 option. AFAIU, OT2 is needed when only ASCII
encoding is available (then one has to use commands for Russian/Cyrillic
letters in a document).

The question is: why you use OT2? Why not fontenc with T2A and inputenc with 'utf8'?

Why you re-invent the wheel? Just add to document preamble
and use macro '\textcyrillic'.

Yes, because root has access to any file and directory while a PHP
script running in Apache has very limited access.

IMO, this was a suggestion to improve your current workflow. You didn't
told any details of your problem, do you use one, two or three languages
in your documents, what encoding of documents, what fonts are

When latex typeset this document it cannot find 'metric files' (TFM). It
could generate them 'dynamically' to use them in this document and in
any other document laterly. But it can't do that while pdflatex is
running by a PHP script (don't have access I assume). When you run the
same document as root pdflatex generates these TFM files but only for
root (check /root/.texlive2010/texmf-var/fonts/tfm).

IMO, the best way to solve the issue with TFM files is to generate them
as root in /usr/local/texlive/2010/texmf-var/fonts/tfm.

There are two sample script: allcm and allec, which you can use to make
alllh, it will generate TFM for T2 fontenc, run it as root. After that copy
directory /root/.texlive2010/texmf-var/fonts/tfm to
/usr/local/texlive/2010/texmf-var/fonts/tfm . This may solve the problem
with TFM files.

WBR, Vladimir Lomov

When the Apple IIc was introduced, the informative copy led off with a couple
of asterisked sentences:

	It weighs less than 8 pounds.*
	And costs less than $1,300.**

In tiny type were these "fuller explanations":

      * Don't asterisks make you suspicious as all get out?  Well, all
	this means is that the IIc alone weights 7.5 pounds. The power
	pack, monitor, an extra disk drive, a printer and several bricks
	will make the IIc weigh more. Our lawyers were concerned that you
	might not be able to figure this out for yourself.

     ** The FTC is concerned about price fixing. You can pay more if
	you really want to.  Or less.
