We attempt to decode everything strictly using UTF-8, then Latin-1, and failing that, we use UTF-8 and replace unknown characters. The localstr class is used to cache the known UTF-8 encoding of strings next to their local representation to allow lossless round-trip conversion back to UTF-8. >>> u = b'foo: \xc3\xa4' # utf-8 >>> l = tolocal(u) >>> l 'foo: ?' >>> fromlocal(l) 'foo: \xc3\xa4' >>> u2 = b'foo: \xc3\xa1' >>> d = { l: 1, tolocal(u2): 2 } >>> len(d) # no collision 2 >>> b'foo: ?' in d False >>> l1 = b'foo: \xe4' # historical latin1 fallback >>> l = tolocal(l1) >>> l 'foo: ?' >>> fromlocal(l) # magically in utf-8 'foo: \xc3\xa4' zUTF-8s UTF-8r% r �! please check your locale settings��hintN)� isasciistr�decode�encodingr �_sysstrrA r �UnicodeDecodeError�fallbackencoding� LookupErrorr �Abortr �bytestr)r& r2 �rr) r r r �tolocal� s2 # & �rO c C s� t | t�r| jS t| �r | S z | �tt�tt��}|�d�W S t y� } zB| t d|j d �|j d � }t � d|t�|�f ��W Y d}~n@d}~0 ty� } z t j t�|�dd��W Y d}~n d}~0 0 dS )a� Convert a string from the local character encoding to UTF-8 We attempt to decode strings using the encoding mode set by HGENCODINGMODE, which defaults to 'strict'.

To deal with this, we take the following approach: - localstr/safelocalstr objects are converted back to UTF-8 - valid UTF-8/ASCII strings are passed as-is - other strings are converted to UTF-8b surrogate encoding - apply JSON-specified string escaping (escapes are doubled in these tests) >>> jsonescape(b'this is a test') 'this is a test' >>> jsonescape(b'escape characters: \0 \x0b \x7f') 'escape characters: \\u0000 \\u000b \\u007f' >>> jsonescape(b'escape characters: \b \t \n \f \r \" \\') 'escape characters: \\b \\t \\n \\f \\r \\" \\\\' >>> jsonescape(b'a weird byte: \xdd') 'a weird byte: \xed\xb3\x9d' >>> jsonescape(b'utf-8: caf\xc3\xa9') 'utf-8: caf\xc3\xa9' >>> jsonescape(b'') '' If paranoid, non-ascii and common troublesome characters are also escaped.

As Mercurial often doesn't know what encoding data is in, we use so-called UTF-8b. If a string is already valid UTF-8 (or ASCII), it passes unmodified. Otherwise, unsupported bytes are mapped to UTF-16 surrogate range, uDC00-uDCFF. Principles of operation: - ASCII and UTF-8 data successfully round-trips and is understood by Unicode-oriented clients - filenames and file contents in arbitrary other encodings can have be round-tripped or recovered by clueful clients - local strings that have a cached known UTF-8 encoding (aka localstr) get sent as UTF-8 so Unicode-oriented clients get the Unicode data they want - non-lossy local strings (aka safelocalstr) get sent as UTF-8 as well - because we must preserve UTF-8 bytestring in places such as filenames, metadata can't be roundtripped without help (Note: "UTF-8b" often refers to decoding a mix of valid UTF-8 and arbitrary bytes into an internal Unicode format that can be re-encoded back into the original. Here we are exposing the internal surrogate encoding as a UTF-8 string.) � �r r# r � �� �i � r )rQ r r0 rA rW rE rF r� rI r rM r} r� r r� r �r& rN r� r3 r' r r r r� w s8 r� c C s� t | �r | S d| vr| S t�| �} d}d}t| �}||k r�t| |�}|t|�7 }d| krddkr�n nt�t|�dt��d@ �}||7 }q2|S )aW Given a UTF-8b string, return a local, possibly-binary string. return the original binary string.
