fix(context): strip hidden special chars on context menu Copy command

[ghiscoding]

• there were some hidden characters that were carried over when doing copy+paste, and the only way I found to fix that was to replace \u034f (unicode char) with empty string
• we should also trim the string to remove any empty spaces from start/end of string
