On top of configuring source control, ensure that your collaborators on any files you share don't have settings that override your encoding by re-encoding PowerShell files. Some of these tools deal in bytes rather than text, but others offer encoding configurations. In those cases where you need to configure an encoding, you need to make it the same as your editor encoding to prevent problems. There are a few other nice posts on encoding and configuring encoding in PowerShell that are worth a read:.

Marcel: No. From the tools I tried, this one was the only that gave precise results, tried Cyrillic and non-standard Japanese.

I understand that it is impossible to determine the character encoding of any stringform data just by looking at the data. This is not my question. My question is: Is there a field in a PDF file where, by convention, the encoding scheme is specified e.
Have a look at page So a PDF library with some kind of low level access should be able to provide you with encoding used for a string. But if you just want the text and don't care about the internal encodings used I would suggest to let the library take care of conversions for you. PDF uses "named" characters, in the sense that a character is a name and not a numeric code. Character "a" has name "a", character "2" has name "two" and the euro sign has name "euro", to give a few examples.
PDF defines a few "standard" "base" encodings named "WinAnsiEncoding", "MacRomanEncoding" and a few more, can't remember exactly , an encoding being a one-to-one correspondence between character names and byte values yes, only 0 to The exact, normative values for these predefined encodings are in the PDF specification.
A PDF file may define new encodings by taking a "base" encoding say, WinAnsiEncoding and redefining a few bytes, so a PDF author may, for example, define a new encoding named "MySuperbEncoding" as WinAnsiEncoding but with byte value 65 changed to mean character "ntilde" this definition goes inside the PDF file , and then specifying that some strings in the file use encoding "MySuperbEncoding". And note that I mean characters, nothing to do with glyphs or fonts.
Different strings withing the PDF file may use different encodings this provides a way for using more tan characters in the PDF file, even though every string is defined as a byte sequence, and one byte always corresponds to one character. So, the answer to your question is: characters within a PDF file can well be encoded internally in an ad-hoc encoding made on the spot for that specific PDF file.
PDF parsers should make the appropriate substitutions when necessary.
