Unicode and StringRegExpReplace issues

Recommended Posts

Now there is another nice toy. Thank you.

Thanks, but I realized I should have swapped the hex order so it can be directly transferred to a PCRE. Here's the fixed version:

$sInputStr=InputBox("Unicode-Hex converter","Enter Unicode character(s) in box to see Hexadecimal equivalents","","",360,140)
If $sInputStr<>"" Then MsgBox(0,"Hex equivalent","Original string:"&@CRLF&$sInputStr&@CRLF&"Hexadecimal equivalents (enter as \x## for values starting in 00, otherwise \x{####}):"&@CRLF& _
    StringRegExpReplace(StringTrimLeft(StringToBinary($sInputStr,2),2),"(..)(..)","0x$2$1, "))

I didn't follow the thread completely and I apologize in advance if this is way off target.

Anyway, here we go. I've transposed into AutoIt some functions I use for one of my SQLite extensions. This is the part where I deal with Unicode casing and unaccenting. I transposed it from C after "some" editing... Please don't look at the code, it's ugly because I didn't have enough time to change the structure of some tables and, to be fully honest, I've little incentive to do so right now.

I believe the Unicode tries are correct as per Unicode v5.1, except for a small number of codepoints that I needed/whished to handle differently from the Unicode tables. The exceptions I introduced are few and I may miss some here. For instance, greek digamma Ϝ, ϝ are subject to casing, german Eszet ß and uppercase Eszet ẞ (U+1E9E) are handled in a special way, finally several symbols are expanded differently by the unaccenting function: fraction symbols use solidus [aka slash] instead of Unicode-recommended fraction bar, ™ gives TM, © gives (.C.) [without the dots!], ® gives (.R.) [without the dots!], all ligatures are expanded, and so on.

Living out the gory details, the OP might well find the _UnicodeUnaccent($str) function handy to do [part of] the job.

Short example (I leave it here so that the fancy characters will display nicely):

Local $s = "éÔµ€kißjàIJçè™…é$énÑÞþÆвℝÅ⁉fiflӸӡӁຳИЙ¼Ϝ½ϝ¾¿ϳʩʪʫʭǽ©ª®ij" & ChrW(0x1E9E)

_ConsoleWrite("_Lower = " & _UnicodeLower($s) & @LF)

_ConsoleWrite("Lower = " & StringLower($s) & @LF & @LF)

_ConsoleWrite("_Upper = " & _UnicodeUpper($s) & @LF)

_ConsoleWrite("Upper = " & StringUpper($s) & @LF & @LF)

_ConsoleWrite("_Title = " & _UnicodeTitle($s) & @LF & @LF)

_ConsoleWrite("_Fold = " & _UnicodeFold($s) & @LF & @LF)

_ConsoleWrite("_Unaccent = " & _UnicodeUnaccent($s) & @LF & @LF)

produces:

_Lower = éôµ€kißjàijçè™…é$énñþþæð²ℝå⁉fiflӹӡӂຳий¼ϝ½ϝ¾¿ϳʩʪʫʭǽ©ª®ijss

Lower = éôµ€kißjàijçè™…é$énñþþæð²ℝÅ⁉fiflӹӡӂຳий¼Ϝ½ϝ¾¿ϳʩʪʫʭǽ©ª®ijẞ

_Upper = ÉÔΜ€KISSJÀIJÇÈ™…É$ÉNÑÞÞÆвℝÅ⁉fiflӸӠӁຳИЙ¼Ϝ½Ϝ¾¿ϳʩʪʫʭǼ©ª®IJẞ

Upper = ÉÔµ€KIßJÀIJÇÈ™…É$ÉNÑÞÞÆвℝÅ⁉fiflӸӠӁຳИЙ¼Ϝ½ϝ¾¿ϳʩʪʫʭǼ©ª®IJẞ

_Title = ÉÔΜ€KISSJÀIJÇÈ™…É$ÉNÑÞÞÆвℝÅ⁉fiflӸӠӁຳИЙ¼Ϝ½Ϝ¾¿ϳʩʪʫʭǼ©ª®IJẞ

_Fold = éôμ€kißjàijçè™…é$énñþþæð²ℝå⁉fiflӹӡӂຳий¼ϝ½ϝ¾¿ϳʩʪʫʭǽ©ª®ijß

_Unaccent = eOμ€kissjaIJceTM...e$enNÞþAEÐ2RA!?fiflЫӡЖາИИ1/4Ϝ1/2ϝ3/4¿ϳʩʪʫʭae©a®ijSS

Edit: posting this way was a bad idea: display is distorded, better try by yourself!

I like this too. You people are just going hog wild building my repertoire of RegExp functions and I just know they are all going to come in handy.

Question about decompiling code? Read the decompiling FAQ and don't bother posting the question in the forums.

I've taken some more time to read he heart of the thread. You guys are confusing ANSI and Unicode.

For instance:

$teststring = '123€ transformed by PCRE(™)'
$teststring = StringRegExpReplace($teststring, "[\x{2122}]", "TM")
$teststring = StringRegExpReplace($teststring, "[\x{20ac}]", "Euro")
_consolewrite($teststring & @LF)

works as expected if you lunch it from a UTF-8 + BOM encoded file. The code posted before was incorrect: 2122 is a hex value and \x99 is a control character in Unicode.

In the same way, the range posted from \x80 to \x9F is a range of Unicode control characters, so there is little chance they match text.

In short, there is no bug at all for me, or there is something big I miss.
