Proposal to add an error message
Recently I've uploaded and installed typo3 on a server with an empty t3lib/csconvtbl folder, i.e. with no charset conversion tables. In result no labels where displayed in BE, it took me about a half of hour to find where is the problem and to upload the corresponding .tbl files.
So my proposal is to add an error message to the initCharset function from class.t3lib_cs.php file in case the conversion table file can not be found. For example like in readLLXMLfile function from class.t3lib_div.php file when the XML file does not exist.

I don't understand why this folder was empty in your installation: It is part of the Core and should always be installed with it. The supplied readme also states that the files are needed in TYPO3.
If you want to have a check, if TYPO3 was uploaded successfully, I suggest to use the md5-hash of the whole Core directories. But I am not sure, if having something like that is really needed... However, if you want to, you are welcome to come up with a patch!
