''' SF_TextStream
''' =============
'''  Class instantiated by the
'''   SF_FileSystem.CreateTextFile
'''   SF_FileSystem.OpenTextFile
'''  methods to facilitate the sequential processing of text files
'''  All open/read/write/close operations are presumed to happen during the same macro run
'''  The encoding to be used may be chosen by the user
'''   The list is in the Name column of https://www.iana.org/assignments/character-sets/character-sets.xhtml
'''   Note that probably not all values  are available
'''  Line delimiters may be chosen by the user
'''   In input, CR, LF or CR+LF are supported
'''   In output, the default value is the usual newline on the actual operating system (see SF_FileSystem.sfNEWLINE)
'''
'''  The design choices are largely inspired by
'''   https://docs.microsoft.com/en-us/office/vba/language/reference/user-interface-help/textstream-object
'''  The implementation is mainly based on the XTextInputStream and XTextOutputStream UNO interfaces
'''   https://api.libreoffice.org/docs/idl/ref/interfacecom_1_1sun_1_1star_1_1io_1_1XTextInputStream.html
'''   https://api.libreoffice.org/docs/idl/ref/interfacecom_1_1sun_1_1star_1_1io_1_1XTextOutputStream.html
'''
'''  Disk file systems and document's internal file systems
'''   All methods and properties are applicable without restrictions on both file systems.
'''   However, when updates are operated on text files embedded in a document, (with the WriteXXX() methods),
'''   the updates are first done on a copy of the original file. When the file is closed, the copy
'''   will overwrite the original file. The whole process is transparent for the user script.
'''
'''  Instantiation example:
'''   Dim FSO As Object, myFile As Object
'''    Set FSO = CreateScriptService("FileSystem")
'''    Set myFile = FSO.OpenTextFile("C:\Temp\ThisFile.txt", FSO.ForReading) ' Once per file
'''
