Character issues like this are difficult to diagnose because information is easily lost through misinterpretation of characters via application bugs, misconfiguration, cut'n'paste, etc.

As I (and apparently others) see it, you've pasted three characters:

codepoint   glyph   escaped    windows-1252    info
=======================================================================
U+00ef      ï       \u00ef     ef,             LATIN_1_SUPPLEMENT, LOWERCASE_LETTER
U+00bf      ¿       \u00bf     bf,             LATIN_1_SUPPLEMENT, OTHER_PUNCTUATION
U+00bd      ½       \u00bd     bd,             LATIN_1_SUPPLEMENT, OTHER_NUMBER

To identify the character, download and run the program from this page. Paste your character into the text field and select the glyph mode; paste the report into your question. It'll help people identify the problematic character.
